Most Helpful Girl
It's mostly individual problems that I see.
Hmmm, widespread obesity and sedentary lifestyles is a major issue, as it is really messing with people's physical, mental & sexual health.
Also, a loss of traditional laborer jobs has hurt a lot of guys who are struggling to find a role.
Excessive porn has been shown to be desensitizing some guys, mentally and physically, as they start to demand sex in ways that most women don't like and/or have trouble keeping an erection or climaxing without constant novel stimulstion. This isn't as big of problem as the first two, I'd guess.
Mostly, that our brains & bodies haven't kept up with technology!1
