I did 15 easy laps yesterday. Things are still pretty good with my knees. I also Did several push ups, crunches and other exercises for my core strength. I feel pretty good actually. But then I dropped a heavy enamel cup on my leg. It opened a hole that I think had a blood vessel coz it bled like hell. I managed to stem the bleeding and now I am in slippers and will be going to the clinic to have it looked at.
