BF,
Its natural that we want to live a happy, satsfying long lives be it forever. Not only for ourselves but for our families and friends. If the paradise will ever come true or not, give it the benefit of doubt. In meantime, focus on the reality not on fantasy, a point stressed by leavingwt. IF God is too good, too compassionate, then he will do something to address the many shortcommings you have raised above but.. not through the WTS, an organisation that has extensively exploited mankind's desire for everlasting life to its advantage.
