There are several different ways to peel a banana

The two principle ways are both along the long way of the banana. It all depends on which end you start on. Most people begin by pulling down on the stem and then proceed to peel it that way. But you could also start at the other end and peel it from there. That way, when you get to the bottom of the banana, you have a little handle to hold on to when you take that last bite. It is a little bit harder to get the peel started going from that direction, but all it takes is a fingernail or you could use a knife. I guess most people think it's just easier to peel it the other way, but I prefer to have a handle to hold, so I peel it opposite of most people.
