My grandmother used to say she bled coffee and ate her weight in sugar and she lived to be 94 1/2. Now, maybe she could have made it to 100 had she not scarfed down butterscotch candies and Hershey's kisses, but she had a *sweet* life. "In all things, moderation" is my motto.
You know, there's a story about some scientists who fed a group of rats nothing but water for several weeks and they died... so the obvious conclusion was that water was hazardous to maintaining life. :P
You can actually "drown" your cells by drinking too much water. It happens to long distance runners when they over hydrate. So back to my motto: In all things, moderation.
*Meh* Tomorrow something different will be bad for you. They can never make up their minds. It's like the whole egg thing. Eggs are good for you! No, wait! Eggs are bad for you! No, wait! Eggs are good for you again!
I just apply my Daddy's motto to everything: "[Drive/Eat/Talk/Act] like you've got some sense, and you'll be fine."
