Does anyone else here constantly, compulsively freak out about how rapidly time passes...

He just said he spent most of his time on hobbies.

30 years old here and in pretty decent shape. Took up skateboarding (something I tried to get into when I was younger but my pudgy fatboy self couldn't handle). Despite the fact that I fucked up by being overconfident (slow and insidious killer amirite?) and opened up my scalp last month, I'm still skating. Why? because it's fun. It gives me something to do that is good for my health (as long as I don't get hurt kek) and entertains me.

You won't be as worried about the passage of time if you fill up said time with rich and varied memories. You only really start to worry about it if you're doing the same boring shit with no real fulfillment.

Well sure, me too, but my hobbies are hanging on the internet and playing video games

What a load of bullshit. The whole time flies faster as you get older is inevitable. Welcome to the future grandpa.
