First of all, "Modern Allopathic Medicine" only deals with ⅐th of the human body.
How can such ignorant people talk about longevity in any meaningful way?

Next, what is going to happen is that people who try to live longer by these methods funded and tried by the aristocracy will now shorten people's lives.
That heart, the one you took from a kid who had no freedom, well that heart is going to remember... and just quit. (and since they didn't keep their half of the bargain for that soul's life, then it is going to come back really painful.)
The elite's lives will be cut short.
"Modern Allopathic Medicine" will shorten people's lives.

The Plandemic has already taken about 5 years off of everyone's lives.
This will become apparent. And then God help those Media talking heads. Body guards will not be enough.

The "Vaccines" (and i use quotes because they had to change the definition of vaccines to call these things vaccines) are going to kill a lot of people and sterilize even more. God help those who administered these "Vaccines".

Lastly, good people who do things such as meditate and live a balanced life with love and joy will start living longer. Much longer. And this will be done in a myriad of ways such as much better food. Energy (sound & light) healing. A far better understanding of the body that will make modern medicine look even worse than leaches.

Further, i must talk about the metaphysical. Not everyone looks for eternal life.
There are many reasons to die.
And once you know God's plan, and how the wheel of life works, you will understand it as walking through a door of your greater life(s)

These things are confirmable to yourself as personal experiences.
There is only a veil keeping your from seeing the bigger picture, from seeing God. And the veil can be moved aside by you.
