Well on an up lifting note you've got a better chance than just 'small' just keep your eyes and ears open as you go along. I'mm sure you'll be fine. There are advantages and disadvantages of being 21 or 39, the obvious age issue and associated life commtiments but also the probability of having some cash saved up somewhere to partially fund your training or even pay for all of it. Compare that to the new young chappie who looks mostly to his/her parents though some still make great sacrifices to get the money themselves.
Come on get on with the research I know you want to and are probably eager to get going. What school are you going to wander down to first .... ?
