My two secrets to staying healthy: wash your hands all the time. And if you can't use Purell or one of the sanitizers. And the other is hot peppers. I eat a lot of hot peppers. I for some reason started doing that in 1992 and I swear by it.
Perhaps we don't need these religious concoctions to pillow the fear of death. Just the fact that there is an unknown and something greater can bring a feeling of peace. That's enough for me.
