I hope you get better soon. I wore my knees out as a young guy too. Between 13 years behind the plate catching a baseball from the age of 9 to 22 and then about five years racing motocross, there's not much left of them. I have bird legs to begin with, so they saw some stress.

They aren't too bad right now, but I know the knee surgery is inevitable unless I get cancer or something first keeping me from reaching a ripe age.

Take care of yourself. Isn't there something you could do for your cars that would be bench work?
