Whether or not 2012 will be our end or if the great tribulation is upon us, why not realize life is short?

It really dosent much matter...if 2012 is the end or if the we are already past the beginnings of the apocalypse...we are all gauranteed that we will face death. Life is short anyway. None of us who are alive have proof of an afterlife. I for one prefer to believe in faith that there must be...otherwise wouldn't a mere 100 years at best for each of us seem irrelevant compared to an eternity?
