I think this question is more important:
Should we have always quantified our health experience as we do today? I think the answer is yes. We could have been healthier than we are today but we just didn't know how to be or didn't take our health seriously enough due to other factors.
If a child eats a bunch of raspberries, they will get a good dose of vitamins and antioxidants and will have more energy. Ever take vitamin C before bed? Didn't we eat chocolate b/c it made us feel better? Didn't we graduate to caffeinated beverages for the same reason? To experience better health? Or was it what we did inherently that we just didn't understand well enough and then we got wiser? Can we communicate the mechanics of food and supplement health experience to a child? Flintstone vitamins have a color that I have difficult to diagnose chemical intolerances of and so I always looked to alternatives. Most daily vits are still made to be toxic to me.
I think that alot of things like this shape who we become and form our attitudes. Perhaps some like me chewed on fred flintstone and thought that all supps were BS for life, but it's built in to survive and be strong and healthy, it's just what we want, what we are as the most advanced species on the planet. We are simply free and self educated to the nth. We are experiencing what others would if only they could. I image that as the vast majority of people aren't healthy in the US given the obesity epidemic, that they just don't think they ever could be healthy no matter what... so those of us who are doing something about it look crazy to the helpless. Obesity is a terrible, progressive disease that leads to accelerated aging, loss of brain function, lost initiative, compromised thinking styles, depression, and so much more. Most just seem to accept it. We should be worried about them, not the other way around.
And of course there are people who just seem to be healthy no matter what, lead perfect healthy lives, feel like they had it better than everyone else and welcome conventional aging etc. There are those with average lives who are satisfied with the cards they're dealt b/c they're better off than some others and they too will likely accept and welcome conventional aging.
For the rest of us, we want more or can't be satisfied easily or adjust to a less than optimal life without fighting tooth and nail. The vantage point of people who aren't like us have continually developed profitable, but less than effective medicine as far as we're concerned and we can do better, faster, and more. We can leapfrog the medical status quo and bring about a lossless revolution where only Death and Aging. We are a Life and Level of Health unto the world! We are not hypochondriacs, we are not narcissists, but we are vain, and vanity is nothing but the outward display of survival, talent, fitness, health, and dedication to the former clouded by circumstance and genetics.
More than anything, people must be attracted to our results and desire to have us in their lives, but we would lose who we are and who we are trying to be. We couldn't be happy without being the kind of healthy that we're working towards and simply can't be happy with such a death and aging acceptance mindset.
