Don't take everything you read like that for the exact facts. How could anyone know that for sure? Besides, if somehow they were able to decide scientifically that information, why would it make a difference to you? Would you really just give up without a fight, if you were told that to be fact? If you were told you had 60 days to live.......what would you do?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
