Last night I noticed a little nodule-like thing on my right leg that I had never noticed before. I immediately checked the other leg and was relieved to find a similar one there, so I relaxed.
Are there parts to our bodies that are not symmetrical (or nearly so)? How about other animals? Any idea as to why the symmetry exists?
And on the “why do you park in a driveway” line, shouldn’t symmetry be a palindrome?
