Strange - that. Are you sure? I have fairly bushy eyebrows, but I often get sweat in my eyes. For example when cycling on a hot day. I don't wear a lid, but I don't know if that would make a difference.
I wonder why evolution hasn't yet given us a gutter in the eyebrow area.

Well it's an answer I read in the New Scientist question page years ago. Of course the helmet issue has nothing to do with it (evolution being around longer than lids!) but brows help to stop sweat coursing into our eyes whatever the activity. I'm sure it's not foolproof and l too, get sweat into the eyes lidded or lidless - but l presume having brows helps.

You could be onto something there. The last century or two have seen in increase in the average temperature of homes in temperate regions, and the last few decades saw an increase in reported anxiety in those same regions. Perhaps the population is becoming more anxious, not as a direct result of lifestyle factors, but due to a natural selection for furrowed brows. After all, a racer setting off from a warmer house will surely start to sweat sooner.

I had a really bad knee all summer. Occasionally while walking I would put a foot down and get a jarring pain, but mostly just achy and not even pain free in bed. But after a month or two it started to be less painful and has now healed completely. So there is hope.
