Seriously - Special Education teachers. I would not do that job for a million dollars, so I salute people who are willing to tackle that challenge.
And this week, I will nominate electric company linemen. Hey, it's a blizzard and an ice storm - power poles are snapping off and power lines are lying on the highway. Go out in crappy weather and fix it.
Compared to that, athletes are not "tough." at least not in the larger sense of the word.
(if you want to see something, google pictures of "power lines down in SW MN." It's been a heck of a week.)
