That is weird. What does it mean?

It means you were born at the same date.

You and roughly 21 million other people on the planet.

*More than coincidence???*

That you share the same zodiac sign as well?

We still might be the only ones in the origins conversation that shares a birthday with anyone else.

Yes, I’d like to be a fly on the wall for the Swamidass/Ham astrology conversation! Although I suspect it would be rather short…

Actually if you pick any 23 people at random there’s a greater than 50% chance two of them share the same birthday. If you pick 75 people at random there’s a 99.9% chance at least two share a birthday. I can explain the math if you like.

ETA: Oh heck, here.

Yes that is true, but if we fix one of them (me) the chances are much lower. As I’m sure you know.
