Somehow, someway, your genetic code (your DNA sequence) will be used in a microchip implant, which ultimately will be a way to identify a person. RFID readers will read the ID info provided on your skin or rather, the implant chip embedded underneath as DNA lab companies will assign a unique identifier linked to your DNA sequence as a means of providing Proof-of-Personhood (POP). POP will be used for cryptocurrency tech uses. In order to protect your financial/identity data, perhaps wiping your DNA will become big business. Did anyone use hand sanitizer prior to the 2000's? Or 1990's? Scientists and the public at large were aware of bacterial dangers but ridding the skin of such harmful microbes wasn't big business until the introduction of an actual product and psych-theory of 'protection'. The widely spread use of hand sanitizer is due to human paranoia. Such paranoid thinking often invades our motives, and ultimately what we buy and sell.
