Great video! Having it explained like this helped me understand more of the function of my immune system.

Beautiful video. On this topic I can recommend the book "Immune: A Journey Into the Mysterious System That Keeps You Alive" by Phillipp Dettmer!

This is cool and everything but I catch every cold my kids care to share 😂 so I’m not sure my immune system is as switched on as this.

Some viruses like the one causing common cold, change their surface proteins to evade the immune cells. That's why we cannot make vaccines for every virus. Some like the influenza change it but not so fast, so you should get the vaccine every year for the more prevalent types of that year.

Cuz they’re bringing in evolved pathogens your immune system hasn’t encountered

I was wondering how come people and babies were so slimy. 🤔 it's good to know it's for a reason.

And having a moist environment ready to go (i.e. wet hair) *wouldn't* increase the likelihood of someone's sneeze or cough near you having an easier time adhering to you while in thin vapor form?
