How do i go about saving and loading?

How does one go about saving and loading variables?
Not from .blend to .blend, but after closing and re-opening the game; still having my HP = 7 or whatever.
I can use python, (Though I’m not the best by any stretch of the imagination) so I don’t need a logic-brick only tutorial. (though that would be nice…)

I recommend to search the resource forum. There are several save/load threads
