I'm confused about this "retirement" thing. In common English usage, the prefix "re" means to do again. Right? Therefore, to "retire" means to "tire again". Yet, when we conclude our working lives, we are said to "retire". So, when we leave our jobs because we're tired of working, we retire and get tired all over again! It makes no sense! Wouldn't it be more logical to "untire" instead of "retire"? I think so.

Happy untirement, MMario!
