My name is Christian Mayer. I am 66 and in fair shape. I had knee surgery in Asia in 1970 and cardiac bypass in 2004. Since that I have quit smoking, walk ~3 miles 4 or 5 days a week and changed my eating habits. Still love burgers but have them with a salad instead of fries now. I am happy with three miles a day since 48 years of smoking has take a toll. Don't think I will ever get it all back. I retired from IBM in 1995 and have been working in the PC industry now for the last 12 years... Full Bio
