Don’t Always Believe the Science

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?

          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.

          10 Small Changes To Make Your House Feel Like A Home

          10 Small Changes To Make Your House Feel Like A Home

          Your house is more than just a building that you live in. It should be a home that makes you feel welcome as soon as you open the front door.

          Making your house feel like a home is not something that simply happens on its own. You need to make some changes to a house when you move in, to give it that cozy, warm feeling that turns it into a true home. To help you speed the process, follow this guide to 10 small changes to make your house feel like a home.

          1. Make the Windows Your Own

          When you move into a home, they often come with boring Venetian blinds or less than attractive curtains.

          One of the best ways you can instantly warm your home and make it showcase your style is to add some new window dressing. Adding beautiful curtains not only improves your home’s appearance, but it can also help to control the temperature.

          2. Put up Some Art

          If you have a lot of bare walls in your home, it will seem sterile no matter how beautiful your paint or wallpaper is.

          Hanging art on the walls will instantly give it personality and make it feel like home.

          3. Improve the Aroma

          A house that is not filled with inviting smells will never feel like a home. There are loads of ways you can make your home smell nice. There are tons of air fresheners on the market you can use.

          Incense and scented candles are a nice option as well. Don’t forget that baking in a home is also a great way to fill it with an aroma that instantly smells like home as soon as you open the front door.

          4. Put out Lots of Pillows and Throws

          A great way to make your home look warm and inviting is to place lots of pillows and throws out on the furniture. It is much better to have too many pillows than not enough.

          There is nothing like the feeling of sinking into a cushiony pillow that feels like a cloud to make you feel like you are at home.

          5. Instantly Class up Your Closet

          If your closet is filled with wire or plastic hangers, it will never truly feel homey. To instantly make your closet feel classy, change out your old hangers for wooden ones.

          Not only do they look great, but they are better for hanging your clothes as well.

          6. Improve Your Air Quality

          One of the most overlooked ways to make your house feel more like a home is to improve its air quality.

          The easiest and best way to upgrade the air quality in your home is to change the old, dirty filters in your furnace regularly. Get some air filters delivered to your home so that you always have some on hand.

          7. Fill it with Plants

          Another way to improve the air quality in your home is to fill it with plants. You should have plants in every room of your home.

          They help to improve the air quality and they look beautiful. As well as making your home appear homier, plants also help to boost your mood and lower your stress levels.

          8. Change the Doorknobs

          Most people don’t really give their doorknobs a second thought unless they are broken. That is a shame because changing your doorknobs is an easy way to add personality to your home.

          Changing your old, boring doorknobs to new ones that are works of art will instantly brighten your home.

          9. Upgrade Your Tub or Shower

          There is nothing like luxuriating in a whirlpool bath or steam shower to make the cares of the day melt away. Your family deserves a bit of luxury when they are in their bathroom.

          Install a new shower or tub today to make your bathroom worthy of a place in your home.

          10. Fresh Cut Flowers

          You can make any room in your house feel homier by placing a vase full of beautiful flowers in it. The gorgeous look and intoxicating aroma of fresh cut flowers will immediately brighten your day when you encounter them.

          You don’t have to make all these changes at once. Try one or two a day though, and your house will feel like a home before you know it. The trick is to constantly keep adding these homey touches to make your home a place worthy of its name.
