> When [Sacks] woke up in the middle of the night with an erection, he would cool his penis by putting it in orange jello.

This is a remarkable sentence, and it appears suddenly in the article without context or explanation.

Naturally, there are questions. Was it necessarily orange jello? Does orange refer to the flavor or the color? What property of this particular jello made it preferable to other flavors and colors of jello? Did he prepare the jello for this particular purpose, or did he have other uses for the orange jello? What were they? Did he reuse jello or discard it after one use? Most important though: why would he do this??

The article does not say.
