My partner and I have been taking care of ourselves since we were 43, and a lot. We gradually gave up everything bad, or almost everything. First it was tobacco, it took me a week to give it up. Then it was fizzy drinks, Coca-Colas, etc. Later came fats, alcohol (all alcohol), and finally ultra-processed products and sugar. I can say that we are now sixty years old and look fifty. It can and should be done. It just takes a little willpower and doing it little by little.
