You are by no means too old!
Finding a flight school is gonna be harder though, I know Ari-Ben down in the Fort Pierce area are pretty good, and they seem to be getting their students through at a nice rate.
Myself I'm going to Phoenix East in Daytona, nice enough school, but the only reason for me attending it as because a flight school in Norway has a deal with them.
Check out the prices and try to get inside scoops from current students at the schools you are considering. No school is perfect, but some are worse than others
