Do not be alarmed. The sky is not falling. Your hair is not on fire. Your family and friends are all alive and well. The world is not ending.
The running that I am referring to here is not running for survival, but as part of a chosen lifestyle.
Judging from what I am hearing and seeing at my school, being a teacher can be a really great job. Sure, you might catch colds from the kids, have to deal with rude and overly talkative children, and complain about not being paid as much as you deserve, but teaching has its perks, too. You receive pension when you're retired, and you can go to school with your kids, if you're like my math teacher (his kids are in middle school right now, so he gets to go to school and leave school with them!). You also get to watch kids grow up and have a hand in how they turn out. It must be really cool seeing your students come back many years later, mature and successful.
The PE teachers have a nice time. They can be outside in the fresh air and have less grading to do than other teachers, but they are paid the same. They can exercise if they feel like it or they can just stand and order the kids to do something. And I don't think you would normally have to work overtime. (My parents still do work at home after they get back at work. I think it's more lax if you're a PE teacher.)
I heard that one of the PE teachers injured his Achilles tendon and it was driving him crazy because he couldn't run. I'm very fearful of getting my Achilles tendon hurt because of how important it is - you could be out for a year, depending on how bad the injury is. It's pretty important in walking and running. It was already bad enough those times I sprained my ankle and kept getting left behind when I tried to run in PE.
I just really wish I could live the active lifestyle. Even the non PE teachers have the chance to pursue athletic hobbies. One time, during PE class, I saw my history teacher jogging on the track. Maybe it was his prep period and he didn't have anything to do so he decided to enjoy the nice weather. I wish I could be as lucky as him, doing a job that I like and also doing one of my hobbies at work.
I am sad about going to high school because I don't think I'll be able to take PE every year. I know I will take it for at least two years, one time in 9th grade, and the other not determined yet. I really want to take PE every year because I fear I will not exercise enough without it. But I don't know if I can. We can only take a certain amount of classes. And it really saddens me.
