Would 당신 give a homeless person CPR if they were dying?

If I Could Do Something To Help A Dying Person Of Course I Would Have Done It !!!!

sure but i'll probably die after that cuz i have asthma

YES

If I knew CPR, yeah.
But I don't, so I'd probably make matters worse for the poor person.

It's actually recommended that if 당신 don't have lip protectors, 당신 don't do mouth to mouth CPR. There is an alternative that doesn't involve mouth to mouth.
