I like the comments you received here. This is despite the fact that in 25 years of cycling I had an event that could have been worse. Had a diabetic seizure that caused a black out last Summer. Had it not been for a sharp eyed Park Ranger and the fact that I was helmeted I would not be here today. Took 2 days to wake up as the fall caused my brain to bleed.
Will this change my bicycling plans. MAYBE. Could be I no longer will travel down country roads without having a quick source of glucose, weather I need it or not.
Sorry did not mean to rain on your parade. Age does have an impact on everything. Never say never.
