We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Body type is relevant to health, exercise, and appearance. It's worth bearing in mind that few people are a pure type, and that, for example, endomorphs can be fat (often termed "skinny fat" - ie a belly on a slender frame) and ectomorphs are not necessarily fat.
The body types are genetic, products of inborn bone and muscle structure. In other words, the body frame.
Thus the reason I do not buy into BMI. Those with more natural muscle are deemed 'higher' on the BMI scale. Need to create different BMI profiles based on body types.
Same should be true for the military. I lost 2 whole pounds after 9 weeks in boot camp while other girls lost 20. I put on a LOT of muscle. STILL was slightly over the weight limits. Had to be taped every single time for 6 years of service. Always passed the tape test.
But not fun to be looked at as 'fat' when I would see short, stumpy girls with huge guts (apple types) who seemed to be able to pass weight requirements.
I am a mesomorph but tend to be thin or at least appear thin. I even had one of those carnival weight guessers miss my weight by a lot. He guessed 190 and I weighed 220. He really believed I had concealed weights in my clothing or shoes.
