I agree about the compromised immune system I will not bore you with all my bullshit I will just hit the high points. I have had ether 8 or 9 heart attacks and ether 8 or 9 surgeries to remove lower intestine and colon. One is 8 the other 9 can't remember which is which sorry. Had a quadruple bypass a total hip replacement. I have a permanent colostomy bag. I had to go under the knife for a strangulated hernia they had to give me several pints of blood. Along with the blood I was given MorgEllons. I have kept a photo journal of the different stages over a 4 year period. Ah hell I am rambling on and on! I apologize, I am sure no one wants to listen to me whining. Thank you for the great information I will put it to good use
