Last Nov. I double fractured my ankle, requiring almost 7 weeks of bed rest and another 8 weeks of casts, crutches, cam walkers and canes, then in late Feb. I had to have left shoulder surgery. I'm still doing PT for both injuries.
Physical Therapy has been a lifeline to getting my health and mobility back and has given me the spark to renew a daily vigorous activity plan.
In additionk, outside of my PT visits (hard to do when your sailing in the middle of Lake Ontario), my PT gave me some elastic bands and excersises that I can do on the boat to continue my PT and condition my body on the days I'm not in her office.
I have also been a long been a proponent of the physical benefits from just standing on a deck. Always moving, the deck provides a constant excersise for your core muscle groups.
One has to be as physically fit as one can be to sail. I think its a great testament to all the ole salties (OJ your included in this) who are still sailing into their 80's and well beyond.
I think an addiction to sailing is perhaps the best fountain of youth there is and I'm looking forward to popping a cork on my 100th at anchor somewhere, enjoying a well deserved sundowner.
