Why women need hip and knee replacements more than men.

         

I've read what the experts tell you. That women are more prone to arthritis and osteoporosis.
I don't buy it. As many things do, it comes down to sex.
     Think about it. Men are usually larger and heavier than women. So, in the missionary position our hips take quite a pounding. Actually, in most positions they do. I'll let you ponder about the knees.
      Why isn't someone researching this? Why? Because most research is still done by men.
