Soooo I've got some awesome news! Just found a new way to look for sneezes!
if you know some sneezy youtubers that sneeze pretty often (I'm pretty sure you do 
) and you are tired of clicking on each vid and going into comment section looking for this lovely bless you comment with timing (ummm I hope I am not that crazy? I've been clicking like 1000+ vids and searching under comment section of every single one... before I found this), you can just type the name of the channel, search for it, click to get videos list, and then choose new vids you need and enter responses to sneezing or comments about it into search section and there you go!!
Hope you have some nice winter evenings searching for sneezes with this method
