No human lives forever at present.
Not one.
All humans are either dead or dying.
There is no blood transfusion that can save a person from dying.
Only Jehovah can give a person everlasting life.
Only God can make a person live forever.
There are half wits in the world who don't realize they're already as good as dead and rather than accept the only blood that saves they choose the blood of the already dead.
The dead cannot give life.
Jesus is alive. He can give life because he has it.
The blood industry is based on harvesting the vulnerable for their bodily fluids in order to sell it and make a killing. "When you really distance yourself from it, it all looks so very very smart and dangerous."
If you want to be "free advertising" for a bloodguilty and abusive industry, then you really are a half wit.
Watchtower is bloodguilty for promoting the blood industry.
