Then consider that in the United States you can literally go years without sitting cross legged anywhere. You sleep on an elevated bed, and you sit in chairs all day, including the chair in your car.
I have a basic cotton mattress on order that I am going to put on the floor, and am giving serious thought to watching TV sitting cross legged on the floor. I even gave some thought to sawing down the legs on my table, but I do want to have some guests more than once.
Still, I think the way Asians do it is likely healthier. We read often about overall longevity of nations, but it is worth pondering how we measure longevity of QUALITY life, as in being able to do most things yourself. Here is one possible metric: median age at which half the aging population needs help getting off the toilet, which would include a support bar. I’m two thirds serious. Everybody has to (hopefully) do it every day. Needing help sucks for everyone.
I have no intention of winding up sick and senile in an old folks home, smelling like shit and urine, and eating once again the food of an infant.
