If you suppose it's all malarkey and conjecture, what is the problem?

When your doctor says that you're wrong, do you accept his advice or tell him he should be more like Dale Carnegie?

Most logical, rational adults would seek a second opinion, at least in places where those are available; they usually are. Interesting that I said 'some people' and you generalised.

FWIW, if my doctor were unfriendly enough, though, I might do that also.
