“Knee deep snow uphill to school both ways” as a simplified “back in my day” I used to hear. Probably a combination of as many as five difficulties the older-than-me generation had to deal with. Pretty few that I can recall.
I have seen dozens of my generation difficulties which have shown up repeatedly in discussions of such things. All because of technology and explosive speed it has advanced.
Future generations will have multitudes of these they can tell their descendants.
