On this day, November 23rd, back in 1963, the first episode of Doctor Who aired.

That was, of course, also the day after president John F. Kennedy was assassinated. I wonder how and whether the convergence of the two affected the memories of anyone who saw the show when it first aired.

But how can one even talk about age in years when different planets will have different lengths of years, and there is no effective way to keep track of one’s age as a time traveler?
