Indeed I am, the good old days sucked compared with now!  And if we're
lucky before the end of the year a fourth detector, KAGRA in Japan, may
join the party; and although smaller than LIGO it might turn out to be
even more
sensitive because unlike the other 3 it's built underground and does not
work at room temperature but is cooled down to 20 degrees Kelvin (-253 C,
-425 F) . I think that is very cool, in more ways than one.
