Yes, I'd like to know as well. I've noticed that as one grows older, the ability to do physical "stuff" becomes a bit more painful. That stuff, of course, includes lifting weights. Hasn't stopped me, though. Just slowed down a bit. :^)
BTW, those were some very good numbers you presented earlier.
I know what you mean by the age thing. I turned 40 this past year and it is getting hard to train hard and stay injury free. I did just have surgery to address my sleep apnea (my dad and 3 of my 4 brothers have/had it as well) In the past month or so I have noticed that my body is beginning to respond like it used to to weight training. Sleep can be such a wonderful training aid!
Hang in there. Somebody has to show yup all these 20-something, pasty, sony-playing girly boy's that society is churning out!
