Enough to last a lifetime

If Food for Thought can be consumed, I guess I"ll probably have enough food, no, more than enough to last me a lifetime.

I think too much, sometimes to the extent of spending countless sleepless nights trying to find an answer to something possibly without any solution (well, at least not known to me). I wonder how much brain cells I must have killed in my crazy attempts to come up with the what ifs in my hypothetical world. But at the end of the day, I find myself asking, do I really have to know?
