I ended the century with a broken spoke, luckily I did not know:)
My old man biked all his life, commuting from downtown Prague to the scientific institute he worked in - 30 miles a day - when he was 63 he landed hard on his face and broke jaw and lost some teeth, he biked the Alps with similar crazy group when he was 65.
Now he is 80 and bikes normal bike and electrical assisted when he feels lazy.
We always biked together when he comes, Skyline drive and such. But because of him, I never got into till I was 40 or so. Started with an old Raleigh I found in a scrap metal bin
Sorry, talk too much as always.
