Okay so if one 70 year old can work, then that means they all are - got it.
There is a major difference between people at 62, and at 70. MAJOR.
Especially in relation to what they do for a living.
I am only 58, but I can't do what I use to do physically now...at 58.
12 years from now I will be severely limited. It would be cruel to expect me and millions of others to be expected to still go to work at that age full time. Outright cruel and inhumane.
I suspect that when I am 70, I will do some sort of work to keep busy and for health reasons. But it won't be a full time job that's for sure. Hell no.
