Indeed, I'm very old; I still run Windows 1.01 on DOS 3.0...
JMI, you're (obviously) right, with regard to the first remark, at least. Neither I'm 85 years old, nor todat is my birthday: it's only a (stupid) joke due to mi childish character, my age regardless

.
Not so about the second remark: you'll be pleased to know that (I'm pretty sure) I'm far older than you anyway.
However, I warmly thank you for your good wishes
Regards
