Do chilled out mice, have a longer life?

Before I start, I know that their (Dwarf mouse) long life is due to their mutation/s in the growth hormone pathway.

But in reading the Bloomberg article, I couldn’t help noticing how chilled out they were !

“ And they’re very chill: Andrzej Bartke, director of geriatric medicine at the Southern Illinois University School of Medicine and a pioneer in the use of dwarf mice to study aging, has posed for headshots with one perched on his shoulder like a parrot."

“ Even during behavioral tests, dwarfs aren’t like other mice, Brown-Borg says. They amble through mazes and build nests under their running wheels. Dropped in a warm water bath, where normal-size mice furiously paddle, dwarfs “spread their legs out and float.” Although this attitude is harder to directly connect to their long life span, it does seem to contain a lesson."

Maybe we should all be a bit more chilled out like the dwarf mouse.

I think it was John Speakman at ARDD that reported an experiment where they held the metabolic rates of mice constant & raised the ambient temp. They concluded that being hot reduced lifespan & being cooler increased it.
