Fyi, you order the 23andme test yourself. Its an at home spit test. Make sure if you help him you dont contaminate the vial with your dna, if you do the test.
One of my write ups on methylation:
Read up on HHV 4,5 & 6. They are common and their implications in chronic disease are just beginning to be discovered, they are no joke if you are susceptible. Alot of people with active infections will actually stop having the viral symptoms, thats usually when things like allergies and sensitivities, other infections, and other complications like neuro or muscular symptoms really start up or get bad. It has to do with how they suppress part of the immune system while upregulating another part of it.
