Last night, I was moving my laundry from the washer to the dryer. Over those machines are some built-in shelves over it, which is normally rather nice for holding laundry stuff and a few other various things. But it wasn't so nice when I momentarily forgot about them and hit my head really hard on it when I was finishing moving the laundry over.
I haven't felt 100% since. In fact, the best I've gotten is about 60%, or possibly 75%. On the plus side, I've caught up on some missed sleep and I got a couple of meals brought to me by Ace. But I'd rather have more energy and less pain.
I don't recommend bumping your head. And hopefully soon I'll be back to normal (I miss having a calm stomach).
