I'm 48 and am having slight problems with my knees from attics and crawl spaces. I didn't start wearing knee pads until about 5 years ago. After 10 sinus infections in one year I always wear a respirator in attics and crawl spaces. Work has been Flat Out, so I refuse the attic work now. Also I occasionally wear wrist straps from the screwdriver work (repetitive stress).

I start every day with a hot bath to loosen up and I'm ready to go. I also roll a tennis ball under my foot to stretch the arch (podiatrists advice!) Also, I lay off the caffeine---shaky hands don't mix with electrical work.

As a final note---it sure beats roofing and concrete work!
