I never even learned how to ride a bike...

^^^your parents disappoint me.

I started longboarding,(if that counts) when I was say 13

I could never get my balance right on a regular skateboard but long boards and penny boards are my thing and I got into it when I was about 25/26

I started trying to skateboard last year, but I'm hopefully going to get a long board so I'm super happy about it

Cousin taught me when I was 8. Don't do it very often but it's fun occasionally. Side note how the fuck do you not know how to ride a bike

Was never taught.
