How much of schooling do you still use to this day?

I impressed three people at work just before Christmas because I converted decimals to percentages and fractions when compiling a report.
Something they said they could never understand how to do.
These guys were HALF my age !

Quite a lot, actually....part of that is because of my career in engineering (so I use a lot of the maths, physics and chemistry).
But I also find most of the conspiracy theories/urban legends/dietary fads and myths that get thrown around online these days can be pretty easily debunked and dismissed with basic high school science knowledge, so trying to retain some of your education is a good way to avoid being fooled.

All of it, I'm still in school.

i think what stays with me the most is HOW to think which is harder to measure in terms of what i remember.

everyday i read things, i add up money, i remember history,sometimes i run for the bus,

A lot. Basic math, grammar, writing skills, and home ec skills.

i use engllish i lerned all the time

I write words
