Can all all of the blood vessels in your body have a total length of 100 000 km? Doesn't seem like it... but I think even I have used this reference in a school project before!

I just want to shout out Kurzgesagt and the fantastic work they always do. there videos are fun, informative and they really put there heart into it all the time.
It helps me stay curious.

If you haven't seen any of there videos before, I highly recommend it.
