No, none of my previous career had anything to do with teaching in a school system. I was tapped to give certain training in my previous career. It was my goal to be a teacher and met all the requirements for a license when I graduated from college, but at that time the market for teachers was bad. They were laying teachers who had 10 to 15 years of experience, so the market for a new grad was close to non existent. So, I went and did other things like work in operations for a bank, work in inventory control for an electric co-op, work as a computer operator and work for local government. Once I retired, I thought I would try volunteering so I did a year in Math Corps, and then got my substitute license. Definitely not the career path for most substitute teachers.
Some teachers do get burned out by classroom management issues and having to deal with unruly students. Most of the teachers I know teach because they care about the students. Some of the students come from pretty bad home situations, non caring parents, parents who do not know how to parent or parents who can not take the time for their children because they work too many hours at minimum wage jobs to make ends meet.
I have been confronted by students, but have never thought I was being seriously threatened. I have broken up fights between students. If I did not think I was doing some good, I would not do it.
Bearcat: I hope you can figure out how to get at least a little comfort from that brace. That thing sounds as uncomfortable as sitting on a cactus.

I'm building a new gaming/crunching rig. Thinking one of the new AMDs and going to get a new GPU also

It's a good time to be in the market for a new (or used for that matter) CPU. Lots of great new options from AMD as well as some good discounted Intel options to compete.

AMD Epyc server chips are now for sale as well 32 core/64 thread for one chip. Crazy. It's not cheap though.

Looking at the AMD Threadripper 1950x 16/32 core
prob toss 32GB of RAM at it
Not sure what new GPU

Glad to see you popped in for a visit. We are all watching the tax package with various degrees of trepidation. I am pretty sure, based on the current information available, that the federal income tax I will be paying will be greater than before the supposed "tax cut." We will have to see what the congressional conference committee decides.
The proposed corporate tax cut to 21% from 39% sounds good for the corporations, but I have seen several surveys which seem to point in the direction of stock buybacks being the beneficiary of the reduced tax rate, rather than an increase in either research and development or better wages for the worker.
The other big problem with the proposed tax package is the explosion in the deficit of 1.5 trillion (1.5x10^12) dollars. The Congressional Budget Office states that there is no way the economy will get better enough to eliminate the proposed deficit.
In my opinion there have been too many special interest groups who want to have their piece of the pie no matter how much it adversely affects the country as a whole. This legislation has boondoggle written all over it.
Just my opinion. I will get off my soapbox now.
Cheers
