I see that birthday spike juuust shy of 70. Nice.

Age and celebrating birthdays get less cool too.

My dad just told me that his high school grad year is officially having its last reunion recently. From the 100 something they graduated with they're down to 35.

They used to rent out big halls for it, now they're meeting at a restaurant near their old school.

What with celebrating birthdays at 60 not being cool?

I love that skateboarding is a half pipe on the graph.

9 year old who's good at patty cake, high fiving a 96 year old who's complaining about young people as they pass each other on the half pipe

I'm too colourblind for this

Living alone is great. It shouldn't drop that low until a fall could break a hip.

Complaining about younger people was never cool.

Wtf is juuling?

40(35?) should be the bottom for skateboarding, and Pattycake recovers once one has or is trusted with kids.

Hell, a 16-17yo that's still willing to play is god-teir older sibling, and the good ones only get cooler with age.

I like how the skateboarding line is actually a half-pipe

this is just a sample of the many types of data a Beta distribution can fit. Would you like to know more?
