i know a combustion engine works lol with the little pistons and cylinders and explosions, the theory behind it isnt all that big but if i had to fix my own car ... that would be like me recommending you to not let me build the house you wanna sleep in, lest you wake up in a pile of rubble.

If screwing computers (as in screwdriver ofcourse) counts then i guess i am but otherwise basically im left at replacing a light switch or a cable hahah

if everyone knew everything then there would be no jobs left instead of 30%, right ?
