Immortality as we know ourselves, yes a bad thing.
40 some years ago as a young white boy aspiring heathen, I remember sitting at the feet of swami guru knows all sees all, etc.
He talked about the future of earth, humanity, and rough times ahead for awhile.
He commented on a time within the not too far distant future when scietists will be able to scrape a sample of skin and recreate any organ in a lab dish. Designer swap out of anything that needs replacement.
He said that human individual lifespan could potentially go on for thousands of years, but for one problem...
Each of our lives as we know ourselves is meant to be only a temporary snapshot in the greater plan. I thank Allah that an infinitude of defective personalities are not going on forever, causing havok with the 137 celestial virgins up there somewhere.
Once the lesson plan for our current expression is exhausted, time to move on. Prolonging the defective presence goes against what we want in a subtle design, and only holds us back. On a deeper level, we want to live forever, but not forever the way we are now.
Old swami guru said that the tipping point, all factors equal, is around 160 years old. Even with the latest and greatest transplants, the entity will begin to withdraw. What we currectly call "failure to thrive". A condition where we have corrected all the electrolytes, verified that all the systems are working like they are supposed to, but the person is still dropping dead. Our patchwork ancestors in the future will get the best organ replacements, but will still opt out of the confinement. Time to move on to bigger and better things.
