It's nice to know that one can keep working with Unix/Linux past age 60 without lethal damage. However, to keep from distracting all the young whippersnappers here with our gray-haired eminence, I suggest we move this to an orkut group I just created, "Old Farts", at http://www.orkut.com/Community.aspx?cmm=52197 . For those who aren't yet on Orkut, send an email with your name and a valid bi-directional email address, and I will invite you in.
