Laid off at 56. When I got home from being notified, there was an email from the HR person at a competitor in my inbox. I started work there within two weeks.

Plus, my prior company had a rather spectacular special severance package for those of a certain age who would sign an agreement not to sue for age discrimination. (This was accompanied by a thick stack of statistics of who had been laid off, showing that they were well prepared to defend themselves from any such lawsuit, but I'd rather take the money than spend the next umpteen years in court, and have the lawyers take any hypothetical judgment in the end anyway.)
