I tend to think as for as the smoker thing goes. Those who started smoking in the era before warning lables and lessons in school showing the black lung would have a case. Those who in this day in age who start smoking ,with fully knowing what it does to you, dont.
as for as obesity thing (I know for some its a touchy subject so I try to speak with respect) topkick brings up a great point on quick judgement on people...but as for as those who sue Mc d's I think Veez post points to those who do nothing for themselves ( unlike say topkick ) I've seen many over weight folks with horrid eatting habits that sit on their butt all day and wonder why they never lose weight. Its the feeling of some that its these folks that turn around and sue Mc D's (knowing full well Mc D's isnt the healthest food) that most people have no Mercy for.
It goes back to being responsible for your own actions. I have training brother who's a larger fellow (but great guy to fight against, built like a tank and one of the hardest training students) tell me he had bad week and just went nuts on Mc D's last week and it was becauses of being in a bad mood. He knew why he did it, regretted it afterwards. He's not going to turn around and sue Mc d's but some other nutters feel they can and their the ones who do less for their health.
just my 2 cents
I will also add I can lose a few pounds myself
damn my terrible love for cookie dough ice cream
damn it to the delicious hell it came from
