Jeez, who are these guys? I'd never heard the phrase, hitting the wall, used in the way you've described it as used on TikTok--but then I'm nearly 80, way past my expiration date as they'd probably see it.

Horribly depressing to know about all this. Stay off TikTok, I guess. Not that I'm tempted . . .I'm not sure I could handle the abuse.
