Yes, there probably is some madness in all of us, it's all perspective after all. One man's normal is another's crazy. For some reason I'm reminded of a man who used to be in my sister's class at school who apparently became something of a hermit. With us being communal creatures normally I guess hermits would always have been considered to be a bit crazy. Sadly this man died a few years ago of cancer and I think it was a few days before they even found him passed away in his home. He would have been late 40s.

That's sad to hear about your cousin and, as you say, a good illustration that social standing and wealth are no boundary for these things.
