Bananas are one of my favourite fruits. Did you know they are technically berries? They're really nice with custard and a really good energy source, so if you're going up a mountain be sure to take banana chips which are dried out bananas that are slightly sweetened.
Bananas are actually radioactive, because they contain the potassium isotope K-40, which is unstable.
Huh... you know, now that you mention it, I did eat a banana split the day before I my x-ray vision took effect... and all these years I thought it was just a coincidence...
