Detail's a good word for this discussion. Everything's becoming more detailed. You could probably spend a lifetime just learning about hair care, not to mention diet, exercise, dental care and the rest and that's just upkeep of your own body. You're not even getting into what you need to know for your given career, general knowledge, history etc.
The other thing's how swiftly and relentlessly things are observed and dissected. I read something earlier about a new face people are puling in their selfies. There doesn't seem to be anything you can do that won't immediately be picked up on and become 'a thing', like what Corpse, Web and I have said before about those 'type of person' memes where whatever you're into will be turned into personality template.
