In Search Of A Healthy Gut, One Man Turned To An Extreme DIY Fecal Transplant (theverge.com)
Josiah Zayner writes: Arielle Duhaime-Ross at The Verge followed Dr. Josiah Zayner, a former Scientist at NASA turned BioHacker, as he attempted the first ever full-body microbiome transplant. She writes "Over the course of the next four days, Zayner would attempt to eradicate the trillions of microbes that lived on and inside his body -- organisms that helped him digest food, produce vitamins and enzymes, and protected his body from other, more dangerous bacteria. Ruthlessly and methodically, he would try to render himself into a biological blank slate. Then, he would inoculate himself with a friend's microbes -- a procedure he refers to as a 'microbiome transplant.'".
He does not. And there is not even a need to be religious to believe in some form of reincarnation. Science is completely neutral (as in "we have no clue") on the question at this time, no matter what quasi-religious "physicalists" claim.
Most ACs are not even worth the keystrokes to insult them. Be generically insulted by this and ignored otherwise.
