I don't think I understand your point. If you believe the headline and think you're more likely to get fired when you're 50+, isn't that a sign that you might have no choice but to "sell your best years" (presumably the <50 ones), if anything?

> Make sure you live a life and have a plan so that when you get fired ... you can still live a good life.

Well yeah, I think just about everyone would like to have both a great life and financial security. The problem is that those two goals can be at odds for some/most people.
