Not if you abstain from touching the screen with your nose.
There are worse afflictions than this one. Are you sure that snail was the same snail? Snails tend to look alike. I had one that always appeared appeared on my front stoop after rains -- it would be there all day, whenever I came came and went, somewhere right at the top of the steps. Then, one rainy day, I whimsically smushed it underfoot on the way out.* Imagine my surprise when I came back and another snail was there, scant inches from the mutilated corpse of it's cousin. My conclusion is they are not so much slow as solitary.It's actually a habit I have developed and is so ingrained
to my essence that I don't see it changing. However, my
lines have gotten longer over the years.
* just kidding. They are no good to eat if you smush them first.
