Well, no more! Because that is 100% false!
I'm bringing this up right now because I've heard this four or five times in the last three days, and it annoys me incredibly. I don't even celebrate Christmas and I love the holiday season because of how cheery people get, and how they seem to be more generous, so people trying to dampen things by spreading misinformation about people dying gets under my skin. So please, next time someone tries to rain on the parade with that line, present the facts.
A bit of a heavy topic for BZP, but I think that saying "Hey, people aren't killing themselves in droves, things aren't as bad as you might think they are!" is an acceptable reason to delve into a heavy topic.
