Why are there so many 35-44 starting their own business? Not because the majority got laid off, but rather they lost the trust to corporate and know major changes will come. Too many have seen with downturns what can and often will happen to people with advanced age level.

If you fall into that position you have some serious problem, because the severance package for 10,15, 20 or more years of service is not a real help. It helps out a couple of months, but than what. What do you have? I am one of early 40 pool and decided not to wait, but rather take action.
