Don't worry about your health, if you are eating these foods now and they are not making you ill, why worry? It's very rare that they cause problems and the health warnings are a matter of covering everyone's backs just in case, so unless you have a serious health problem, carry on doing what you enjoy doing!
On age and elderly, my great great aunt used to maintain that you went old until you were 80, once she reached 80, it became 82, 84, 86 etc as the years passed by. It's wasn't until she was well into her 90s and did develop health problems that the time to be counted as old ceased to be an issue, it just was never mentioned again. Life is for living, not for stressing about age and silly stuff like that, if I want to be daft and irresponsible, I'm jolly well going to do it!
