I went to your brother's site, and wow - he is amazing. I have a hard time dealing with my various illnesses (some are chronic), and if there's a secret on how to maintain a positive outlook, every single day, year after year - I'd like to know what it is. That said - I whine sometimes, ok, I whine a lot. I do have a couple of reasons though - not only do I not feel good physically (never mind mentally/emotionally) but when I cough, people tend to move away from me or give me this 'look', and I don't get to defend myself. Instead, I feel bad for being sick and I can't blame them for thinking I have something contagious, when I don't. See, I just whined.

Does your brother get these 'looks' - though perhaps, for a different reason?
BTW - a cousin of mine got hit by a drunk driver once. Ironically, he (my cousin) committed suicide not long afterwards.
