Very sad for sure.
However the comment from zzyzcentral.com is a little dissapointing to hear:
"It is a sad day for all of those whose lives Zyzz inspired and motivated. The best way we can cherish his memory is by living life to the fullest, by training hard, getting aesthetic and not taking life too serious."
Surely what we can garner from this is that we should be taking life a little more seriously, yes?
