I was in a bookshop with my son the other day. In the computer section I saw a book called" Computers for the over 60s" I am 82 and have been programming since the days of the c64 in c basic Pascal and Modula 2 ( remember that?) and now C Sharp.i might write a book called Computers for over 80s, but it ptobably would not sell in any great numbers. The point is din't make assumptions about oldies, we are all different.
