Problem for single person is to make good gourmet vega you need to use many bowls,pans,etc. I don't know if vega extends life, but affords a quality life. I believe that each person should live life as they choose. It takes time to adjust to straight vega food regime,but old desires disapper after a short time. When I was a kid I learned to use salt before I even tasted food.
Salt is a very easy thing to elemiate.
The food value is destroyed in the process and the sodium content is soo high. I geta kick out of people who say had great breakfist 2 slices of toast loaded with butter and don't forget hash browns fried in oil. I get kick out of health ads. As far as I know there is about 7 companies that make vitimans. They are marketed under various names.
