Mr. Edmond Halley was Astronomer Royal in England, born today in 1656. There is a comet named after him, because he figured out that it would show up every 75 (or maybe 76) years. Mr. Halley was 27 when the comet flew by, its solo appearance in his lifetime.
Rhinos are not gifted at counting. Our system is to keep looking up, in case it is 75 (or maybe 76) years now. Time is tricky stuff, and you never know. Well, We Rhinos certainly don’t.
He wore a wig. Very chic.
