The old question about the chicken or the egg. I always think it has to be the chicken as God didn't make Adam or Eve babies. I haven't gotten very far in my 'The Science of Happiness' but it seems from studies done that there is a 30 % healthier side to happy people. The question is are healthy people happier or is being happy make you healthier? I do not have an answer yet but maybe it will seem to get answered as I continue reading. So in case it is that being happy causes you to be healthier, keep smiling and always see that glass half full.
