It depends on what the treatment is and what you, will gain as a result of it. If you are going to have a much better quality of life afterwards and it will make the remaining years you have left much better, then perhaps so. Let's face it, getting older is hard enough as it is, what with ailments, illnesses, lack of money etc, adding an even less quality of life due to something that you could do something about is something to consider.
you have to weigh the pros and cons
@classic33 and only you can answer that question, but, if it can change some of your problems, then id think about it very seriously indeed. After all you have peole who can remind you of the good times as well as the bad times, and you can still make new memmories, and given a second chance, you can perhaps make changes in yourself and your outlook and attitude, and maybe you can be a better person.
yes our memories are what makes us the people we are, but there are circumatances where drastic measures may need to be taken. But, think very carefully
