I sincerely hope the doctors weren't kidding me about how strong my heart is and stuff, because even standing on my feet was exercise after trying to propel my manual lawnmower through the short but desperately tenacious grass. I don't remember it being that hard last year. I wonder if I need to get the blades sharpened. It is as if they are just cutting the grass with some kind of karate rather than like a knife. If I lose speed (due to moss, which there is too much of) I get stuck. Not having sharpened this thing in two years is also kind of suspicious, is it not? Back on the farm we would never let anything go without maintenance for two years.
