Strenuous

I was doing strenuous yard work the other day (for a friend, I would never have a house much less a yard) and I found myself drastically out of breath. It was very scary. I experienced the type of exertion that I normally felt after playing soccer or basketball—now after a few moves of the shovel. Also, when I lowered my neck, I could feel a slight pinch which I believed was cutting off oxygen to my brain. What a mess.
