But is it healthier enough that there is any reasonable measure in ones life for not squat shitting? No. So people can say it's 'healthier', but if there's no tangible difference in the long run, then it's just words. People have been shitting in sitting toilets for centuries.

We hear things are healthier, but it's important to understand if that is a meaningful word or not. The fact that a toilet exists is far healthier than the alternative of no toilet, and far more meaningful.
