Being just shy of 31, and I feel something like that coming. Kind of depresed me lately.. Especially after I started loosing to 20-somethings in BJJ quite regularly :-)
FWIW, you're probably in your physical prime right now, barring weird circumstances. The "losing to 20-somethings" is probably just a run of bad luck, or you happened across a particularly talented group by happenstance, or you're losing focus for some reason, etc.
For most men, you don't really start declining physically until your late 30's or even into your 40's. Then you start getting drops in testosterone, etc. But, the good news is, men (and probably women to, not sure on this point) can gain strength and muscle mass well into their later years. You may have to work harder in the gym to keep up, but don't feel like you became a frail old man at 30 or anything. I'm pretty sure I know some 50 year olds who could kick all our asses at BJJ. :-)
