I agree. There are a lot of very vocal sub 40 year olds who complain about their health/bodies. Myself being one of them. It's because we feel we shouldnt have to worry about this stuff until much later in life.

I'd wager than the majority of reasonably healthy people don't have any major health/body issues until their 40's when the metabolism starts to slow significantly and their former healthy lifestyles have to change to maintain the same level of health.
