I almost posted this in IMHO as a “too stupid for GQ” type question, but I don’t think I would have got the kind of responses I’m looking for.
When I look at the hairs on my knee, I see many hairs that are in pairs, probably about a millimeter apart. They seem to occur much more often than would be expected by chance, and indeed, the hairs on my thigh and calf are more or less evenly spaced, with not a single example of the double hairs I see on m knee. What’s the deal?
