some people in old age complain of stiff joints. what is the possible reason for it?
I just read the other day that coffee makes you stiff! Well, I have to have my morning cup, stiff or not! Also, we lose muscle beginning around age 30.
Try some of the following links for information:
The synovial fluid between two bones get dried up as the age increases and two bones start rubbing with each other.
