One thing I've noticed with adults compared to adolescents is the "puffiness" of adults. It's not just that adults are overweight and have a greater fat mass, it's more like a general inflammation or along those lines.
I sometimes try to guess the age of a person from behind. The giveway clues for youth are shinier hair, a faster walking pace, and a general "tightness" (even if they are overweight). Many adults tend to look more bloated, independent of their of weight.
Are any doctors even looking into this? I'm sure this puffiness is not a good thing. With all these medical tests today, you think they could come up with a test for this, given that it's obvious from a visual standpoint. I know there are blood tests to measure inflammation (like CRP), but I'm not sure this is the same type of inflammation I'm talking about.
