I was talking to an older man who works at my petstore, he breeds ball pythons.. he keeps them all on a rack and he told me his oldest one is in it's late twenties..
Just drop it with this bins vs. tank crap. When kept in a bin, heat and humidity are easier to keep stable, therfore better for the snake.
I'm guessing your one of those people who keeps their snake in a 55g fish tank?
