At the age of 68 (in June) and having been a Type 1 diabetic for 52 years the wear and tear is starting to negatively impact my bicycling.
But, only temporarly
A couple of months ago I chaffed my right foot (while walking 20K steps a day in a month-long team event) and developed a pressure ulcer that is
still taking it's time to heal - another week or 2 and it will finally close. It was complicated by getting infected and after several swabs and different anti-biotics that issue ended. Now healing normally with Manuka honey, high tech dressings and simply off loading weight with crutches. Back on the bike by June, I thought...
Then 3 weeks ago was diagnosed with a blood clot/hemorrhage (macular degeneration)in my left eye and a cataract as well. Emergency operation here in Doha and a 7 day hospital stay to make sure there were no complications. Amazing recovery but I notice some degeneration in the left center of the vision field. Back to work this coming week.
No matter, going travelling in July and August with my lovely. She and I will be taking 2 Bromptons for short jaunts in Eastern Canada, the UK and maybe France.
Life is good.
Excellent fact , as I just heard an old friend from HS days died of stomach cancer.

Moral of the story is: pedal
as often as your body allows you to do so - and listen to your body so it will treat you well
Reciprocity is rewarding.
