These are just lazy rationalisations that allow you pat yourself on the back for 'cleverly' dismissing thousands of scientists and doctors who have spent their lives conducting hundreds of thousands of highly repeatable studies on millions of people over decades to come to the same conclusion.
Yes the same conclusion, which is usually so ambiguous as to render it futile. And it's not lazy rationalisation either, that's a phrase a politician might use when doing blah, blah, and does nothing to support your opinions, generalisations rarely do.
At least be honest and just say "I'm probably going to increase my chances of the leading causes of death, but it's worth it to eat meat and fish and egg and dairy."
Last time I checked I wasn't required to make any personal statements regarding death and the inability to avoid it, it might be more honest as you indicate but that would also require me to give a rats behind about it in the first place. True honesty, in my own case, is that simple, I really, really,
really don't care. I don't care what other people do either, I wish them luck and let them get on with it.
Then why do you bother seeing a doctor for anything? Everything he knows about every medicine he gives you is discovered the same way.
I trust doctors less than I trust plumbers, and I don't trust plumbers at all. A doctor is good for a) a week off occasionally b) stronger pain medication than I can buy over the counter. Other than that it's flowchart time, is the patient this, is the patient that, yes/no, then it could be a,b,c or d.
