I've never heard someone call it the "blossom end", I've always known it to be called the Bananus (banana anus). I think monkeys typically open it on the same end rather than from the stem.

The kiwi skin on is actually very fibrous, I know someone that was constipated during pregnancy and the only thing that would clear them out was kiwis with skin on!

I eat watermelon seeds. Watermelon not hard enough to need to bite down hard and it's too time consuming to spit out every seeds. They do not collect anywhere in the GI track.

I do all these, except with bananas I split the skin along the entire back so the peel is one solid piece instead of a dangly mess.

I break bananas in half to start peeling. Otherwise no matter what end I usually end up crushing the point of the banana.

Fuzzy fruit makes me gag.

I've mostly switched to only opening bananas from the butt end, and I think my friends are about half and half.

I also enjoy the kiwi skin. Witnesses are almost universally disgusted and some are ready to throw hands.
