Do you truly trust anyone?

Do you truly trust anyone?
When I say truly trust, I mean 100% trust someone, say if your life depended on it.

Can someone truly trust anyone? If it came to them or you, the majority of people would choose themselves over someone else, even someone very close to them.

I only have a couple of people in my life that I trust a lot, but even then its not 100%.
