At an interesting website called you.regettingold.com, you can enter your birthdate and compare, among other things, how distant things are in the past compared to how old you are now.
Turns out that my birthday is closer in time to the first powered flight crossing of the English Channel in 1909 than it is to today. The upside is that almost 90% of the people born on my birthday are still living, but almost the same percentage of site visitors are younger than me.
I suppose it'll be interesting to see what historical events my age approaches -- or is it distances? -- as I hang around the planet.
