Curious about calories?

A Pre-SI unit of food energy.
Replaced (really?) by Joules.
Each one becoming part of us.
So, how many do you need?
How big do you want to be?
Check the label.
I do.

New is good.

Unless it isn't!
We learn by experience.
And if it feels good, we generally label the experience 'good'.
And do it again if possible.
Repeated too many times it may become 'old hat'.
Then we need to move on to other new experiences and learning.
You agree?
