No worries whatsoever! Ah...the afterlife is good...Here is an article that will give you two simple test to see if you will die within 13 years... It for the brave of heart... @rittmeister , @O' Be Joyful , @Wehrkraftzersetzer , @Jim Klag , @jgoodguy , @diane , @Leftyhunter So read and test at yourself risk of knowing....
