A Science Nostalgic writes "I'm 38, have a successful career as a software developer but feel the all-too-similar enterprise apps are boring my brains out, and I'm intensely missing the world of science, which I didn't pursue in favor of programming when I got my engineering degree. Now, I'm contemplating a job in research, but fear the age and the lack of 'exercise' with math and physics would pose an understandable handicap. If I study math seriously, I can realistically shed the 'rust' in a year, maybe two, but I still fear I'll be considered too old for research. I graduated abroad so I don't have any old contacts at the local universities (there are a few in my city). I checked their job boards, and they have no positions for research, just the usual ones in software development that I could use as an entry point. Do you have any experience with such a career change? Is it feasible at all to get into science once you approach 40? I feel my brain is still alive and kicking, and years of debugging have taught me a few things about investigating causes and correlations, which are useful skills in research."
