I think it's really sad, and even infuriating, that people are telling you that 26 is too old. Really. So tell me: when is the "cut-off" age? at what age does one have to choose a career that they stick to forever and ever??? Is their opinion, then, that you should be a teacher for the next 40 years because that is the decision you made at 18? Ridiculous.
To me, you are only too old to return to school when you are dead.
