I'm coming up on 49. When do the aches and pains start?
The only aches I get come from the weight lifting I do (5) days a week to stay strong.
Depends on what you did in your youth...the more damage done early on, the more aches later on. Resistence training is great, but I hope you're being smart about it and wrapping your knees/using a belt. My right knee is about shot now from years of aggressive squat rack/dead lift work w/o the proper precautions. At 49, you should also be in the 'maintenance mode' and not trying to achieve new personal bests!
My aches have increased significantly in the past year or so (at age 52)...this coincides with moving from a modern house to a midcentury home needing tons of TLC. I don't have nailers and such, so most things are done old school w/ lots of impact to my elbows and wrists...this is where I'm suffering the most. Also my knees, hips, and low back are feeling it from all the lifting/toting/etc. associated with installing new windows, renovating doors, installing flooring, landscaping, yadda-yadda, blah-blah...oh, and moving everything I own. Yeah, this shit was a *lot* easier in my 30s/early 40s...
Wah. I'm still on the right side of the grass, can ride my thrux, sail, get it up, and lay it down. Lots more to be grateful for than to complain about...and when I do need to cry in my beer, it can now be a quality IPA instead of that crappy big production brewery stuff we had in the past. Its all good.
Cheers,
