I've never thought about it

I think they mean your birth and death day ?

Oh, of course. But technically most of your days aren't exactly 24 hours long. Most days are 23 hours and 56 minutes.

I missed my 18th birthday When I crossed the dateline going to Japan on a ship. We crossed the day before and zipped straight into the day after. True story.

Does this mean that you're always a year younger then yourself?

I was just coming here to say the same thing -_-

Then that someone is fucking awesome
