The word "normal," like many words, is polysemous (has multiple meanings). Normal can mean typical or average - when we say people "normally" lose muscle as they age, nobody is claiming that it is preferable or ideal to lose muscle, they just mean that it happens to most people. But in other contexts "normal" can
mean adhering to some norm - some standard of correctness. Like the result of a Pap smear. An abnormal Pap smear isn't a good thing. An abnormality on a CT scan of your brain doesn't make anybody happy - it's not a sign that you're super smart, it means you might have a tumor or a brain injury. In those cases "normal" confers judgment on its object - to be normal is good; to be abnormal is bad.
A significant problem is that because we think with words, when those words are ambiguous or have multiple meanings our thoughts can become confused. If we don't keep in mind that the different senses of the word "normal' are unrelated we can get caught up in various fallacies. We can start to think that since eating bread is normal (in the sense that it is typical, or that most people do it) that it is good (in the sense that a normal Pap smear is good) or acceptable.
I'm not just talking about uneducated people - the medical profession commits this fallacy all the time. Ask most physicians about what you should do if you are over 40 and your hormone levels are significantly lower than they were when you were a teenager. Most will say that your condition is normal - meaning that it is typical of an aging American - therefore they will not treat it. The same way they wouldn't treat a "normal" Pap smear result - there's nothing to treat. The problem is that while dropping hormone levels IS typical, it IS NOT good or healthy. There IS something to treat there - an illness that happens to be shared by the majority of the population is still an illness.
Imagine a 19 year old college athlete went to the doctor and complained that they weren't as athletic, lean, explosive, or able to recover as quickly as they "used" to. Contrast that with a 45 year old with the exact same litany of complaints. How do you think their treatment would differ? I bet the 19 year old would be offered a battery of tests and treatments. The 45 year old would be told to rest more and take up some less strenuous sports.
It's NOT normal to eschew sugar and grains; to train hard while aging; to seek mastery of a physical discipline while still working a job and supporting a family; to train for extreme performance; to expect the health of a teenager as you pass 30 or 40 or 50. It's not normal in the sense of being typical or average. But it's not abnormal either, not in the sense of an abnormal Pap smear.
Be un-normal. Embrace it. Strive to achieve physical goals that leave others shaking their heads; live a lifestyle that makes people think you're a freak.
And if you doubt yourself - if the thoughts that being abnormal is bad start to creep into your head - go down to the nearest mall, sit near the food court, and take half an hour to watch "normal people" waddle around the tables. Listen to them wheeze and huff and snort. Then ask yourself if you really want to be normal after all.
