I completely forgot gyades - my apologies to him. So I do know more than one astrophysicist. Although it would be fun to meet still more of them! (Even if it does remind me that I set out to become one myself, back in the Upper Cretaceous, with notable lack of success.)

Maybe it's the following year that my beloved offspring and his wonderful wife squeektoy42 will be doing what it is they'll be doing. Time flies when you're having fun ;-)
