Doesn’t dive too deep (fun footnotes tho) and covers a lot of ground with many many metaphors to explain complicated concepts easily. Great intro for those curious but wouldn’t recommend for those who already know a decent chunk about stuff. Either way it’s a fun read with beautiful visuals and ai still learned and had fun while doing it.

From my 9yo: When my mom first bought it for me, I thought it was one of those long boring books, but when I actually read it, I found it deeply interesting. It is casual and conversation like, while exploring deeply into the immune system.

Immune does what it promises on the cover: it takes you through a fairly high-level tour of how your immune system is composed. It's high-level by necessity. If you look around, there are literal tomes about the immune system because there's just so many things going on at once and things we don't know.In Immune, you'll learn about everything from macrophages to the thymus. You'll learn interesting things like how infected cells release cytokines, and while these are what lead to inflammation, these are also part of an incredible cascade that activates other parts of your immune system. (If cytokines freak you out, wait until you learn about what neutrophils can do.)You'll also learn some surprising things. For example, there's no real way to "boost" your immune system, and you wouldn't want to even if you could! As it turns out, our immune systems can be pretty aggressive, and for the most part the balance between activation and deactivation can be a delicate thing. Your immune system, if over-activated, can actually hurt you...which makes sense if you think about allergies and autoimmune disorders.If you want a "boosted" immune system, the best thing you can do is eat an at least OK diet, exercise, and manage your stress.Another thing that struck me is how a lot of the immune system feels random. Yes, there are receptors, proteins, etc that different cells react to, but considering how small they are compared to us, it almost feels lucky that these different cells can meet at all. Of course, your heart pumps your blood around, so that helps, but it's just striking how something so effective can have no sentience or sapience.The chapter on how vaccines work was very informative. The entire book is informative and wonderful to read (minus the author's tendency to use "in a nutshell" everywhere). This isn't one of those stuffy books where you feel like you're reading a college textbook. You'll learn about the immune system through various metaphors, such as battlegrounds and hotdog buns.A fantastic book. Worth every penny and minute spent on it.
