I used to donate blood, but sadly a medication I take prevents me from doing so anymore. One time I even donated two units since they were particularly low on that type. You have my respect.
I also help do compatibility testing for an emulator, though life has kept me from doing that recently.

That’s the other thing, too. It’s rare to be in a situation where you could inhale it. The only example I can think, which is also a rare situation, is if a vehicle that uses it is involved in some kind of accident and breaks the piece of carbon fiber. That could release it into the air causing you to breathe it in.

If you want a more literal, chemist answer: carbon fiber. Carbon fiber’s chemical structure is surprisingly similar to Asbestos. Even though we barely use it for anything due to the difficulty in producing it, it’s most likely just as harmful to us as asbestos.
