Former England cricketer, Adam Hollioake (Australian-born) has recently written about the best way to unzip a banana. Most people, myself included, tend to gain access to the fruit by pulling down from the stalk.
Hollioake advises entry from the other end, like our animal cousins do, and on this recommendation I can confirm that his findings are correct.

well that's a relief!!

Where do i buy a copy?

that's the way I also do it and can also confirm it's correct
