Ah, the sweet, glorious, gold-tinted days of when I was....uh, twelve. No, ten – I'm barely twenty now, youth would be ten, surely. Half and half.
Gosh I'm so old. What did I do when I was ten? Um....Played with LEGO. Didn't have a computer. Ran around with sticks. Ate ludicrous volumes of junk food in summer days without getting fat. So much time. Such memories. I was still in Montessori and had barely met current lifelong friends.
I'd ignore school for the first few years and learn German or French or both. I'd stick a toe in Chinese, maybe Russian. I'd run thought experiments on my new age cohort and sit enraptured and fascinated by the responses of the ten-year old mind.
Gee, ten, I can't imagine being ten.
Honestly I'd probably just run around and be ten.
At some point I'd hijack my dad's computer and get him to buy buy buy bitcoin (was it still low back then?) but not much else.
