An anonymous reader writes: I have read some stuff on Dice.com's message boards where some people are claiming that after age 40 or so that jobs become very scarce in the IT profession. I was wondering how prevalent this really is, and in particular I was wondering how hard it would be to actually start a career in IT or Software Development at age 40.
I recently finished up a degree in physics, and I have done a little basic IT support as well as some programming as part of my job working in an environmental testing lab. How difficult would it be to start a computer career at age 40, and what industries and fields will have the most problem with my age and which will have the least problem with my age?
