The second blog I ever read was Paul's, and I chanced on him by accident by clicking "Next Blog" at the top of the page of the first one I ever read. As you may know if you've tried it, this normally leads one to the rantings of illiterate teenagers, so I count myself very lucky to have found Paul.
He's 85 - must be coming up for 86 now - he lives in California and he's a hoot. We've been exchanging long emails for about four years now as a result of that lucky click. This is his picture, shamelessly stolen off his blog - http://www.oldprof.blogspot.com/ or click on the link on my blogroll.
Do visit him and say hello if you don't know him yet. You should read his second-last post ("Things Old Professors Do") before you read the last one ("Sheez!") , or you won't get the full effect. I want to be like him when I'm 85. Except not a man. Preferably.
