Yea, I got one of those yesterday... "come in for a mobility assessment." OK, do you want to see how fast I can ride my bike?
I also get lots of mailings from the "help I've fallen and I can't get up" people, as well as incessant mailings from various retirement and assisted living places. Don't start me on AARP, either. They have given up on me, but not DH, who is a couple of years younger.
I am pretty sure it's age and income targeting.
