I agree with many things that you say. I am 52 and still ride and hope to only stop riding the day my heart stops, for what ever reason. I do hope that retirement will help me to ride more and not be so stressed due to the present job. Riding has been the thing that allows me to relax from the work related stress. I look at Ken Kifer and really hope to find my same type of niche that he has found balancing out retirement, activity, biking, diet and working on his web site.

Many of the people that I see with worn out parts are due to excessive weight vs. excessive exercise. I do not know if this is the typical view but from my spot in rural Ohio this is what I have seen.

Keep riding, keep power walking, keep young at heart and mind are certainly keys to the success that you and your wife have experienced/.
