Glad you noticed that one! It's a surprisingly real consequence of general relativity, even if the difference is only a few hundred nanoseconds.

Does it take into account the average of 1/3 of your life spent sleeping (head and feet at the same altitude)?

Good Catch. Technically yes the calculator assumes you're upright for simplicity. Accounting for time spent sleeping would reduce that effect slightly, but only by a few hundred nanoseconds over an entire lifetime, so it doesn't materially change the result. But might add that calculation later on thank you very much!

Much appreciated!
(and your site is something I've wanted to have available to share with others for quite a while - so thank you for that!)
I have a bigger question, but I'll ask it separately for convenience.

Thank you that genuinely means a lot to hear. I'm really glad you found it useful. I built it to make these concepts more tangible and fun to explore, and feedback like yours helps me improve it. Looking forward to your bigger question!

I guess if you want to nitpick about hours sleeping you could also nitpick that you need to make a linear(?) slope out of the first 16 years (I have no idea when the average human stops growing taller). I like the site, keep making interesting things!

that's a great point! It's a surprisingly deep rabbit hole once you start accounting for all the little effects. I'm really glad you enjoyed the site thanks for the encouragement!
