6p7702 | why do women scream when startled while men don't seem to have the same reaction? | I was watching a prank channel on YouTube which has a lot of jump scare kind of pranks. I noticed that most of the time (trying not to generalize), the reaction of a woman was either a physical twitch with a short yell/scream while a man on the other hand still had the same physical reaction but would say words like "O... | explainlikeimfive | https://www.reddit.com/r/explainlikeimfive/comments/6p7702/eli5_why_do_women_scream_when_startled_while_men/ | {

1evgqc | why do cds cost less than mp3 downloads? | I've noticed that most albums cost *less* when bought as CDs than MP3s, even though CDs contain higher quality audio and buying the CD gets you a free MP3 download of the same track. Examples: [Les Miserables](_URL_1_) and [Random Access Memories.](_URL_0_) Why is this?
