I have learned something just now (talking to the doctor helped).
I knew this before, and you, wise reader, probably know this already, too. But the mind is like a onion, with many layers and each layer has to learn the lesson and hopefully, someday, the vital knowledge makes it to the core, and it doesn't have to be learned again.
Drink plenty of liquids and eat your veggies.
There you go.
Hopefully, I have expidited a layer of learning for you, dear reader.
