Few of us boggle - though we should - at the fact that Louis Armstrong sang and played trumpet with similar panache, or that Leonard Bernstein and Benjamin Britten were equally adept as composers, conductors and pianists.

The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life.
