pretty sure LOX recommended this product:

i started taking 4 pills twice a day a few months ago hoping to get some relief from sore elbows, aching knees and nagging lower back pain. honestly, the product must help because, now that i think about it, i have had significant improvement in all of the three areas i mentioned.
i started climbing at age 30 and in a few weeks i will have been climbing for twenty years. i think i'm just really starting to get the hang of it. over the past two years i made physical and technical progress by trying harder to work on fundamentals and having fun. this year i am hoping to do the best climbing of my life - if i can continue to progress, and if i'm lucky and can stay healthy and free from injury.
whenever i hear somebody younger than me bitching about getting old i can't help but think of the time i hiked a few hours up Mt. Olympus in Salt Lake City before turning around one summer day because i was tired and didn't have it in me to finish to the summit. on my way down, just as i was thinking to myself about how i was getting old and feeling sorry for myself, i was passed by an old guy with white hair who was running and on his way up. He looked to be at least in his upper sixties. except that because he was shirtless i could see his torso was cut like somebody half his age and he was running at a pretty rapid pace.
my mind was blown. that was the day i realized how stupid it sounds for anybody younger than that guy to ever complain about, or use age as an excuse.
