When I was around 15 I used to do 10 hours of x86 assembly programming, and then several hours every day after school for a month or so in a row. Parents would have to force me from the computer.
I attribute it to a younger brain, NO internet and NO fun distractions. At 42 I just don't see how I did it, and I know I could never be that focused. Just sitting still for 4 hours make me feel quasy now, and I need to use my physical body in some way.
Yea I miss youth. I'm in my 30s and all nighters are not the same anymore :(. When I was young I'd do 2-3 in a week and with a four hour nap I would recover.
Now after those I lay down and I can't get up for a couple hours with all this aching in my limbs lol.
