While a chapter could have limits (or just feel uncomfortable about pledging someone a lot older). I don't think Panhel can.
So I agree with all of the above. Someone who's 25 and is more of a traditional student (stretching the definition a bit) would have a better shot than a 39 year old non-traditional student. But that's all campus culture and such.
