Don’t Always Believe the Science

Science has given us some amazing inventions over the centuries. Personally I’m a big fan of the light bulb (thanks Thomas) and the Wright brothers were certainly having a good day when their flying machine finally took to the air at Kitty Hawk all those years ago. But I guess the scientific breakthrough at the very top of my list was created by that little-known inventor, designer, engineer and scientist… Ogg.

    Who would have guessed all those millennia ago when Ogg emerged from his cave to invent the wheel that not only would he make his and Mrs Ogg’s life a crap-load easier but all these years later my favourite toy (my motorbike) would be totally dependant on his neolithic creativity and invention.

    So thank you Ogg from the bottom of my high-octane heart.

    Science impacts on virtually every part of our lives. It is something we consider, negotiate and benefit from every day. It’s also something which misleads us and confuses us from time to time. Ask five experts one question about nutrition and your head might explode from the variety of answers. Ask ten conditioning coaches or exercise scientists one question about training and we might find you two days from now sitting in the corner sucking your thumb. Or visit ten medical experts with one condition and you’re likely to get numerous diagnoses and more prescriptions than you can poke a stick at.

    Part of the problem with some scientific ‘facts’ is that they aren’t facts at all; they are scientific theories.

    Every day somewhere in the world another scientific ‘fact’ bites the dust. It is exposed for the fraud that it is. I could give you a hundred examples of this but I don’t want to put you to sleep, so instead I’ll give you a few things to chew on which might be relevant and of interest to you.

    1. Height/Weight Charts

    To say that a person should weigh a certain amount because they are so many inches tall is not only misleading but potentially dangerous. Stupid in fact. At best, these charts are vague indicators or guides of what may be a healthy weight range for some individuals. We have a rugby team here in Melbourne, Australia called the Storm. If you were to compare the weight of the individual players against the ‘scientific weight recommendations’ for their height you would discover that close to one hundred percent of the team would be classified as overweight or obese. And therefore all fall into the high health risk category. When in reality the only immediate health risk to the Storm boys is getting their heads ripped off by some unhappy neanderthal opposition players. According to ‘science’ I should weigh somewhere between about 12 kgs (26lbs) and 22 kgs (48.5lbs) less than I do right now. My body fat as I write this is 16% (healthy). If only I was seven feet tall… my weight would be perfect!

    2. BMI

      BMI stands for body mass index and it is a scientific formula used to classify people on a scale from underweight to obese. The equation is:

      Your weight in kilograms divided by your height (in metres) squared.

      Here’s my BMI equation

      91 kgs divided by (1.78m x 1.78m) = 28.72.

      This result tells me that I am significantly overweight and borderline obese. Hmmm.

      This science doesn’t factor in how much muscle individuals have.

      Check this out:

      Subject one:
      Male
      Height 180cm: (5’11”)
      Weight 100 kgs: (220 lbs)
      Actual Body-fat: 12% (low)
      BMI classification: 30.9 = FAT!

      Subject two:
      Male
      Height: 180 cm (5’11”)
      Weight: 80 kgs (176 lbs)
      Actual Body-fat: 25% (high-ish)
      BMI classification: 24.7 = NORMAL!

      Scientific crap.

      3. Girth Measurements

        The other day I was chatting with one of my trainers who asked me what my waist measurement was. She wanted to see how I rated on the scientific table which estimates my health risk (potential for disease) based on my waist measurement. According to the ‘science’, blokes with a waist measurement over 40 inches (101.6cm) are in trouble and girls with a waist measurement greater than 35 inches (88.9 cms) are at much higher risk also. Fortunately I’m a fair way under the danger zone but this science is flawed also. It’s vaguely indicative but by no means absolute as it doesn’t factor in the height of the individual. Surely a 40 inch waist on a guy who’s 5’4″ can’t be compared to a 40 inch waist on a guy who’s 6’7″? Well, apparently it can. And then we’ll call it a health risk assessment.

        Is waist measurement an indicator of potential health risk? Sometimes. For some people. Is it good to use a ‘set figure’ (in this case a 40 inch waist measurement) to evaluate the potential health risk for an entire population? Er… nope. Could a bloke have a 35 inch waist and be a higher risk than another bloke with a 40 inch waist? Of course.

        4. Recommended Calorie Intakes

        Dr. Bumnuts: “Okay, let’s see Mrs Smith… you’re 5’6″, you’re 42 years old, you currently weigh 70 kilos (154 lbs) and you have a sedentary job. Therefore you need 1,650 cals per day to maintain your current weight and 1,150 cals per day to drop down to 65 kilos (143 lbs) over the next ten weeks.”

        This almost sounds plausible. And if Mrs Smith expended the exact same amount of energy every day (1,650 cals worth of energy in this case), then the expert would be speaking the truth. But naturally our energy expenditure (how many cals we burn) can and does vary greatly from day to day. If Mrs Smith spends Saturday hiking, rock climbing and wrestling bears (as she does), she might need 4,000 calories just to break even for the day. But on Sunday as Mrs Smith and her sore muscles recline on the couch for the entire day, her energy needs will be drastically reduced – perhaps to as little as 1,200 calories. Same body – different needs. Bodies requirements vary from day to day which is why I always encourage people to learn to drive their own body rather than just following some generic one-approach-fits-all driver’s manual. The Point? Our energy needs (calorie requirements ) are not ‘set’ so consuming the same number of cals each day is not necessarily smart science.

        5. High carb, Low carb, No carb, My head hurts.

        Advertising

          I’m not going to explore this debate in detail here but I will say that there are numerous books, studies and experts which (who) totally contradict each other on this subject. The interesting thing is that many of the conflicting theories on the matter are backed up by indisputable ‘scientific fact’. Sound scientific research. Sure. Sometimes scientists are compelled to find a way to support their hypothesis. If you know what I mean.

          6. Australia the Fattest Country.

          A couple of weeks ago here in Australia we were informed by the scientists that we are now the fattest country in the world. Here are two excerpts taken from a leading newspaper Melbourne Herald Sun:

          “AUSTRALIA is the world’s most overweight nation, ahead of the notoriously supersized Americans, according to a new study.”

          ” The report, released ahead of the federal government’s obesity inquiry, presents the results of height and weight checks carried out on 14,000 adult Australians nationwide in 2005.”

          So in a country of 21,000,000 people they tested 0.06 percent of the population which means that they didn’t test 99.94 percent of us! I have two questions:

          1. How do they know that the 0.06 percent is representative of the 99.94 that they didn’t test?

          Advertising

          2. Why would they use an assessment (height/weight chart) which is scientifically flawed?

          Science is an incredibly valuable and necessary part of our existence, survival and development here on the big blue ball and I’m passionate about it. I’m also passionate about not being mislead or misinformed. We can learn and benefit so much from so many clever people in the world of science but like anything that involves humans, it’s flawed.

          Thanksgiving: It’s About The Simple Things

          Thanksgiving, a day of pure gluttony, football, and possible uncomfortable situations with family members that you may or may not like. Oh, yeah, and the whole “know and reflect on what it is to be thankful and grateful.”

          During the holiday season many people forget what this time of year is bout and are too worried about getting the “early-bird” deals on Black Friday and making sure that they have the perfect gifts for their loved ones. I am sort of a “Grinch” when it comes to the holiday season, mostly because of that mentality by many of the poeple around me.

          But instead of being grinch-like this holiday season, I decided to simplify things and get back to what this time of year is actually is about; being thankful for what I have and what I can give.

          Simplify

          I’m not a “minimalist” in any real sense, but in the last few months the talks of Patrick Rhone and others have got me to rethink my stance. Can you really have too much stuff?

          Absolutely.

          And with all that stuff comes the burden and the weight of it on your back.

          Advertising

          If you feel that the things around you are out of control, maybe it’s time to simplify and be thankful and grateful for what you have and use. Here are a few things that you can do to simplify:

          • You know those gadgets in the drawer that you said you were going to sell? Well, time to get the listing on eBay and sell them. Or, send them to a place like Gazelle. Even if they are old and won’t get money, you can at least recycle them.
          • Get rid of things you don’t need. Like old books, clothes, tools, etc. Have something that’s been laying around forever with no use? Donate it to a charity or church. If you aren’t using it, someone else could be.
          • Find your productivity tools and stick with them. Use tools and gadgets that serve multiple purposes so you can simplify your tool set.

          Be Mindful

          You don’t have to be a master Buddhist or meditator to be mindful (although, it can definitely help). Being mindful comes down to being cognizant of the present and not keeping yourself in the past or future. It’s about living in the moment and being aware of yourself and everything around you. It’s just being.

          Without getting too “California” on you, it is super important to be mindful during the holiday rush. Rather than worrying about the things that you forgot at your house on the way to relatives or thinking about the next stop in your endless holiday travels, just breath and think about what you are currently doing.

          Advertising

          Spend the time with your family and friends and don’t crush the moment. Try not to concentrate so hard on getting the perfect photo of the “awesome moment” of the day and actually miss the awesome moment.

          Being mindful over the holidays will help you be with your families, friends, and yourself allowing you to enjoy your time.

          Reflect

          As the year is coming to a close (yes, it really is that close!) it’s a great time to start reflecting on what you have accomplished and what you haven’t. Within the next few weeks we will have a more throrough reflection article here at Lifehack.org, but reflecting every now and then over your holiday break is a great way to see where you have been doing well in your life and where you need to improve.

          Advertising

          Reflection shouldn’t be used to “get down” on yourself. Reflection should be used to take an honset inventory of what you have accomplished, how you handeled situations, and what you can do better. If you journal everyday (a daily form of reflection) it may be a good time to start going over some of the things that you have written and start to put together a year’s end journal entry. I mean, how else will you write your autobiography?

          But, seriously, reflecting on yourself makes you aware of your successes and faults and helps you plan and make goals for the coming year. It makes you a better person.

          So, while you are stuffing your face with bird, stuffing, and mashed taters’, remember that the holidays are much more than the superficial things. Use this holiday to become a better person.
