Rubbery bananas. [View all]

I googled but could not find the answer, though others were asking too. Does anyone know why periodically I will buy bananas that look good but they are rubbery. When I try to break them up for my smoothies they just bend, not really break up easily and the smoothie is so thick cause the banana did not break down normally in the mixer.

Curious, .... Gotta find the answers, lol.
