While you were working outside, you didn't happen to feel, like... a pinch or something on the back of your neck, did you..?
I felt a severe cramp in my left calf, if that counts for anything.
No that's just you getting old.
I'm 20. Pushing a mower for 6 and a half hours does some things to you.
I'm sorry, but at least you can have lemonade and some food while working?
