I'm 40 yrs old, and it will still be another 3yrs before I can return to school, but I think I've finally figured out what I want to be when I grow up - a civil engineer. I'm using this time to relearn Physics and calculus. A part of me doesn't care if I'm too old, the same part that shrugs off doubts about whether I am smart enough, because this is what I am passionate about and I'll continue to pursue this interest one way or another. But I would still like to know if I will face many significant challenges due to my age if I try to pursue it formally. While I do have over 100 credit hrs, those are mostly not applicable to this degree, and so it will still take me about 4yrs to finish school making me 47 yrs old when I graduate. I should probably mention that I'm female.
