I'm beginning to wash my hands more often. It's a good thing to do. However, a couple of days ago, I realized that I haven't been washing my hands long enough. I've been told that you should sing Twinkle Twinkle Little Star in your head as you wash your hands to time yourself.
This works great in that you wash your hands for a full 15 seconds, but singing Twinkle Twinkle Little Star is a real waste of thinking time. I've timed myself, and it takes around 15 seconds to pray the Our Father in my head.
So now, whenever I wash my hands, I'm praying. This is two good habits at the same time.
Oh, by the way, don't forget to wash your thumbs.
