Not sure that's a good way of asking. The pain of being veg seems to be inversely correlated with knowing reasons for going veg, and there's a lot of loss aversion. I got anecdotal evidence from quite a few people telling me that going and staying veg is actually much easier than they anticipated. (It's important to take the time to learn about health effects, look at meat alternatives and find veggie restaurants). Reversal test: Imagine you're vegetarian and earn $3000 more than you currently do. Would you pay $3000 a year ($8 a day) to eat meat again?
It's not only more ethical but also healthier to be veg.
It makes me happy to see you and others taking action due to Peter's post.
EDIT: Concerning the "although", I recommend to also read Brian's comment.
You should read the results of the first study you posted more carefully:
Cohort studies of vegetarians have shown a moderate reduction in mortality from IHD but little difference in other major causes of death or all-cause mortality in comparison with health-conscious non-vegetarians from the same population.
The other links don't contradict this study, and only look at deaths from specific causes, and not general mortality.
