I'm rather late in responding, Wayne, partly, but not entirely my fault, as you probably know. Thank you for showing us your son (?) at work, a & thank you for all your very kind comments on my recent photos. Merry Christmas & a very Happy New Year. Best regards, Rafi I attach a photo of Rachel, my wife, & a colleague at Rachel's computer,doing homework. Rachel is the one holding the mouse. In the photo behind her you can barely see me, as I looked about 40 years ago with the, then, director of the hospital I worked at.
