I remember seeing this really cool spaceship-themed immune system video in school about 7 years ago. I don't remember the name, but I'd love to find it and watch it again. Does anyone know what I'm talking about?

The silver lining to colds and flus has always been that at least my immune system is better for it, and I’ll be less likely to catch the next thing. However, I’ve caught 3 colds (or something- they were all different, and none were serious) this year and it’s only May! In the past I’ve caught maybe one thing a year. Does your immune system stop improving as you get older? Why do old people get sick more easily? And how old are you when that starts? And how possible IS it to reinfect yourself with the exact same virus or bacteria? Once you’ve had something, wouldn’t your immune system just whomp it the next time it came by?
