Forget dropping the kids off at the pool - should we be taking our poo to the bank instead?

While you might be thinking about banking your savings now for later in life, two experts from the US say we should also all be thinking about banking our poo. They propose that people could bank samples of their own poo when they are young and healthy for potential use in a poo transplant later in life, to help rejuvenate the bacteria in their gut. There is already one personal 'poo bank' open in the US where people can bank their own poo for future treatment of gut infections. The experts say that more well-designed animal and human studies are needed before this approach might be feasible on a large scale - but they say it could have the potential to treat diseases such as asthma, multiple sclerosis, inflammatory bowel disease, diabetes, obesity, and even heart disease and aging.
