If I read another article suggesting the best way to deal with apparent labour shortages (first of all, where?) is for people to continue working long past retirement age I'm going to scream. I know it's hard for you (Boomers) to contemplate your mortality but you cannot live forever. And therefore you cannot work forever. And therefore this theory is BS.
The actual solution is for you to retire gracefully having trained someone to take on your role. Who will then gracefully do the same. This is the natural order of things. Not working til you are senile and all of the young people have slit their wrists. —Young and Close to Leaving
