Topic on Talk:Are there any advantages to having a slow personal tempo?

I was talking to a friend and she said that "Our ancestors needed fast reaction time to predators and the like but also constantly firing off maybe led to too much adrenaline release and stress so those who had slower times had other benefits that put them at an advantage." I found it interesting and perhaps there could be something there!

There is a correspondence with less stable environments leading to fast life history strategies. So if fast life history corresponds with faster reaction times and general speed, then your friend may be on to something there.
