I have learned the difference between “your” and “you’re”.

I find it takes much, much longer to heal from injury. That’s the main downside I’ve experienced. When I say longer - when about 8 yo I broke my arm, it took 5-6 weeks to heal, maybe 10 to really heal, stop swelling ever and feel exactly like the other. When about 45 I broke my finger and it took 2 years to fully heal and feel like the rest of them.

But it also takes longer to get mad, I’m less irritable, more perspective I guess. Easier to feel happy/satisfied, too, it’s closer to the surface now.

You can’t stand grindy videogames. You see young adults as children, and their behavior becomes irritating.

Your perception and outlook on time changes a lot.

Everything seems to go by faster. Waiting for something doesn’t seem that bad when it’s in terms of days instead of hours, weeks instead of days, months instead of weeks, years instead of months.

When making long term plans, “how long you think you’ll live” becomes more and more of a factor.

Your first gray pube.

Presbyopia

The amount of candles on you’re birthday cake are so numerous that the fire department comes out.

You look at your weekly pill container to know what day of the week it is.

Making interjections when standing up, from a chair, from bed, getting out from your car seat, etc …

One of the biggest and most terrible things that ever happened to my province, which CONSUMED everything for a long time back when I was a teenager and people still talk about very passionately to this day, well meeting someone who has NO idea what this is makes me feel old.

Pimples just becoming permanent weird little bumps

You measure time on the scale of emergency to emergency.

My 60th birthday.

It’s daytime. Or nighttime. Or evening or morning. Or you don’t know what time of day it is but you’re conscious. Any of these situations indicates aging is happening.
