    One of the key players of our immune system is the complement system. An army of millions and trillions of tiny bombs, which work together in a complex and elegant dance to stop intruders in your body.

    I really enjoy your videos! Especially the immune system ones, so I hope that you'll cover all parts of the immune system, one by one, because that would be very interesting to watch, as usual, thank you for your hard work!

    I'm a programmer and this is something I'd actually like to turn into a game. Maybe take the concept of the Dyson sphere video and turn that into a game too!

    This is so fucking insane and complicated that I am in awe at all the scientists who spent entire careers figuring this out for us.

    It would be cool to have a video game based on this. Like Call of Duty style where you will play as a protein and you will kill benign cancer cells, etc. There are also bosses and unlockable characters. Imagine learning while enjoying.
