I ran two miles today. This is my first run since January 7th. I had not problems. It was exhilarating in fact. I feel very 'up' right now due to the various stuff that comes with human Endocrinology. Next up is a trip to the local dump to discard old plants.
I am really enjoying being in shape. Yes, I feel stiff and sore at times. However, the rest of the time the sensations are wonderful. I out perform many of my younger co-workers (or so I am told). This is not at all what I thought 50 would be like. I started my half century mark by climbing the highest mountain in Douglas County. I have continued by running, skating and riding my bike (I should hit 2000 miles on my bike this year).
The science on aging is really interesting. We have learned that our feet work better without shoes, sleep eight hours straight is not normal and that maximum nutrition with minimal calories increases health and life.
As I am enjoying my healthier lifestyle there is still room for improvement. Which takes time but will come. I plan on following my 91 year old pop and go down kicking and screaming.
