Of the great climacterical year, that is, sixty three

Now I know what the problem is! I am now in my grand climacteric year. I am in the "mysterious period of life when the the numbers of seven and nine multiplied into each other" (see quote). According to Sir Thomas Browne, this is a vulgar error. Hopefully I will escape this dangerous year.

I now have to wait to see what happens when I'm 81.
