Welcome, I took took up biking again (40 year break) at 61, 2500 miles the first year, even more so far in 2016 and just ordered a new Surly Disc Trucker to do some touring this fall. We live in Florida, so like you, we can bike all year. October is by far our nicest month! Get the bike, ride every day you can. I got it for some exercise/therapy due to shattered leg injury, so far I've lost about 45-50 pounds although that was not really my goal. So that means lower cholesterol, blood pressure, etc. I also don't feel at all guilty for riding to a local beer pub to have a cold one with my friends
