I too about 3 years ago was also very poorly , didnt eat for a month , lost a lot of weght , at the same time lost all of my strength. Now I am back to normal and eat sensibly, no definitely not salads , cant think of anything worse than being doomed to eat salads, I dont dont have floppy ears and a bobby tail (behave before you comment). I am happy as I am. Mother lived to be 96 but had Alzheimers/dementia , knew nobody for her last 10 years, was violent at times. What is the point. Yes live long but only if you have all of your faculties. By the way she smoked most of her life and liked an occasional drink (of course didnt drink when you asked her but Lord help you if you opened a bottle) she snacked on crisps etc. Chocolate bars in her late days she could annihilate a large bar of chocolate, no problems. .
By the way I joined a gym , they didnt say you had to go.
