Let's just say that today is actually Saturday, and that the day after tomorrow is yesterday. That would mean that yesterday is Friday and tomorrow would be Thursday and today would be Wednesday. Now if the day before Yesterday (Friday) is Tomorrow (Thursday), then what is the day after this day; (Tomorrow/Thursday)... The answer is (YESTERDAY!!!) :-))
Nope... Just think when you die you go to the most wonderful place... Heaven.
When you're in heaven there's nothing to worry about.
Generally all humans are afraid of death. Even religious ones. Because everyone always says 'What if there is no Heaven?' at least once in their life. I bet you do too. You should just think about the present and enjoy it, buddy.
