My overall career choices would be the same regardless of my lifespan. If i lived to see 80 that would just provide me with more time to achieve my goals. If i only lived to 40, that would only make me cram my goals in a sense. Now if everyone lifespan was reduced to 40 or 50, than education would more than likely be pushed earlier and harder. This could possibly result most completing undergraduate school by 18. I personally believe if you have certain goals you wish to achieve you must do whatever to obtain it regardless of your lifespan. You have to strive to fullfil your goal because tomorrow is not guaranteed.
