Oh for Pete's sake, Dale, stop being stupid about this and get the advice of professionals who have the credentials to be dispensing such advice.
If you are not able to handle the task with your aging cognitive abilities, please ask your wife or sons to help you. Shopping for a variety of conflicting answers on the internet is silly and not very helpful for you.
Sorry to be so blunt, but you don't seem to be hearing the same advice given nicely by others.
Please, Dale, you deserve better than this. Ask your family to help you figure this out.
