OK, Could be. But he normally keeps his age a secret!
Don't give your knee too much rest. You have to find the right balance. Often things will only heal when used properly (but not overused). I had this experience with an inflammation of my achilles tendon (after two years of rest it just wouldn't get better) and with my sewn together quadriceps tendon. After the operation my knees where really bad! I patiently did the exercises recommended by the physiotherapist and later found that walking down steep hill would strengthen the knees significantly.
