For the life of me, I can't see how it's possible to just choose to believe in something without the introduction of some kind of evidence. People appear to, I know, but I can't fathom the mind which can do that and be anything like 100% convinced of their new 'belief'. It must take quite a degree of mental strength to overcome such a fundamental hurdle. I couldn't do it, however great the potential resulting 'comfort' may seem to be. Each to his own, I suppose.
