question: Hi I have a 90 yr old friend who had congestive heart failure a year ago in November.  He continued working beginning in Feb of this year. He says his brain just isn't working. He is not remembering how to make the machines he's made for 30 years. He and his wife grow all the food they eat,  and all of it is organic. I'm thinking it is the meds he's on. He is also wetting him self several times during the day and night.
