I am 63 and doing well but have picked up a condition of acid reflux during the last decade that makes it necessary to go without food for several hours before bedtime (which I should do anyway). Have picked up a spur heel but use "Molefoam" next to it and an Ace bandage around it over my sock and it doesn't bother me unless I do a lot of walking without those items on. Taking a thyroid supplement nowadays and wear +2 glasses around (except when riding) and +3 for reading (used to have 20-20 vision).
Not getting much riding in this summer as I'm working like heck on my house while I'm off work. Once I retire for good I plan on riding about every other day or more. Would like to get back up to a couple hundred miles per week that I did in my 30s and early 40s.....perhaps not as fast miles as then.
And in 10 years?
Who knows? Life is a crap shoot. But like my sister says: "The secret is to keep moving".
