Thank you.

CRISPR can be used to modify the adult genome of some tissues. An adenovirus is used to deliver an retrovirus payload. One biohacker created one all by himself in a borrowed laboratory and cured his lactose intolerance in his intestines by taking the virus pills by mouth. Then he could enjoy pizza for the first time in his life without explosive diarrhea. It's an amazing video.
