Is over 30 an issue? I would think this is time to hit your stride. Often this is getting towards a decade of experience that can see skills peaking and bring a bunch of experience and know-how to a team.

Maybe surviving after 40. More realistically surviving after 50 is a legitimate question in my mind.

OK, that's good thought, hehe. I am forcing myself to improve a lot, not for this current job, but to catch up with the community. I am not sure I can continue doing it after 30, cause too many things to learn and gonna burn out myself.
