(let's see how this will age) I am very healthy for my age. People look at me and they tell me I look 12-15 years less. I am not strong but I am lean. I don't smoke, drink, do drugs, I eat 'well'(?). My blood tests are great, I 'move' a lot. I do squats and push-ups every day (irrespective of going to the gym) I don't fear for my body, that thing will take me to 110. I fear that my mind will give out at around 80(?) and I will live 30 years pissing and shitting myself in some 'home'. So I starting considering my 'exit plan' in case I start losing my marbles. I don't want to be a burden to anyone, and waste any wealth to a nurse wiping my butt. I prefer to give as inheritance and/or donate anything I got, and then call it a day/night/life.
