Pain (among other experiences) exists as a gradient compared against both your average experience and any outlier experiences (good or bad). A result of living in a more comfortable, advanced society is that things that seem smaller to someone on the outside are bigger on the personal level. These people aren't inherently weak or soft, it's just that the worst thing or day they have experienced is pretty good in a global sense, but pretty bad in a personal subjective sense.

Depression magnifies emotional and physical pain.

Lack of recent exposure also makes people weak. They need to get back in practice or it's like they're skipping the gym to veg-out on the couch with Netflix, weed, and a case of Doritos.

If you want to up your social-pain threshold, say "hello" strangely to 200 random people.
