Maybe osteoarthritis kills it slowly. Overuse does too: consider football linemen: tremendous pressure every play on the knees and hips, and ergo many hip and knee replacements in that group. Spike - it's just age, old buddy. You can try glucosamine/chondroitin and it probably won't help. Avoid injections if at all possible: there is a very limited number of them you can have, and to boot, they damage tissue too, as does any steroid. You want to save the injection until the pain just begs you to do something. And when the injections have to stop it's time to consider replacement. Getting older is dealing with pain, no way around it. You could also try some anti-inflammatories, such as Naproxen, curcurmin, aspirin, and so on. bill </span>w<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'>Ja, OK but what was wondering is what physiological changes occurred over time such that teenage knees come bounding down the stairs but mine don’t?

The songs were mostly from the 50s, a few from the early 60s which at that time was only 20 years old. Their definition of oldies in music was 20 years. Sheesh. Well OK then, plenty of us who were teens noticed the “oldies” were generally better music than the… newies. It was cool stuff, Elvis and Everlys and Roy Orbison and so forth.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Comic Sans MS"'>There was is a hip mod group but by now it would oldies: the Cranberries.
