@sandw40 As we age and sit more/move less, and if we want to live well for another few years, I think anti-coagulation makes abundant sense. It's just that there are perhaps better options, at least at first, in the early days of aging, say from 60-80 for many of us with 'long genes'. One better option would be to clean up the diet. Another might be to haul our coats out and move our carcasses just a bit more often....and more than just once around the block and nip back indoors to the digital devices and their siren calls.
