one of my co-workers was like that, she has asthma and would smoke like a 3 packs a day. she would always be coughing, have attacks, be in the hospital for her lungs and still would not give it up. I would tell her that she should just give up smoking for her health and she would say "ya know, i love it so much and if i die, i'll die happy"...until one day she had an attack that was so life threatening. actually she died like 5 mins from it, heart stopped, too much air in the lungs, they had to use the "paddles" on her. she was in a coma for 4 days hooked up to machines.

now she's doing better, doesnt smoke, cleaning up her life, asking me all kinds of questions about the truth. so sad what some have to go through to appreciate life.
