Well, I guess I just joined the club (Dec 1945 birthday)! I too have very little in the way of health problems--just a bit more weight than I should have. I found an interesting article in a PubMed search today:

http://www.ncbi.nlm.nih.gov/pubmed/21148220

I liked his conclusion (and he got that published in the British Medical Journal), as I have three bikes. Rrydabent, I also have a Rans Stratus, it it has over 10,000 miles on it now. I just replaced the front brakes (back breaks to be replaced later this week) so I can get it going again. I have a Rivendell Rambouillet too, as well as a Trek 1420. I have the Rambouillet equipped with a handlebar bag, and racks for two bags in back. The Stratus has a neat fairing, and can handle both front and back bags. Right now the weather here in Oregon is pretty nasty, so I only get out on holidays and weekends. I still work, but it is a 12-15 mile one-way trip, with a nasty climb over the Portland Hills. If I want to avoid a really twisty road (Germantown Road), I need to go through Forest Park on a fire road. So that will probably wait for a better time of the year.

On my rides, I normally go between 12 and 20 miles, sometimes into the hills (when I can see them--when I cannot, it's too rainy and nasty to be up there). I have several really nice routes just north of Beaverton/Hillsboro, Oregon and end up at the Great Harvest Bakery, where I buy our weekly allotment of breads (Harvest White, Honey Wheat, Dakota, or some specialty breads) to take home along with "samples" (pieces from their bakery that they give away to people who come into the store). It makes for really pleasant biking.

Anyway, I'll be looking in here every once in a while.
