Do you think the latter is what the OP is asking? Not from what I've read in this thread.
I will also say that while age may not matter in most cases in terms of seeking funding, seeking employment is an entirely different matter, even in academia.

I am really trying VERY hard to focus on the narrow aspect of what the OP is asking. The tendency of many threads of PF is to deviate into areas well beyond what is being asked. The OP was quite specific in what he/she is asking, and I only try to answer that. This, despite so many people trying to pull this into different directions.
The issue of employment, and even the possibility of going to grad school, getting a PhD etc. at a more mature age have been asked in a number of threads already. They have been addressed!
