Blood Work

I've heard mentioned by Andy Galpin that the ratios between different hormone levels is a great indicator of subjective experience of health and vitality. What are some the more more important hormones to get measured and ratios between various hormones to aim for? Thanks so much!

pain & sleep

I am 77 years old and have tried all your recommendations for sleep. Pills, 8 pod, set sleep and wake up times, light in the morning, a dark, cool room at night, exercise several hours before going to bed, intermittent eating, vitamins, I eat a light meal several hours before going to bed. I also meditate, journal, and use my hot tub. I do not watch stuff on TV or other devices; when I nap, I do so in the early afternoon and no longer than one hour, and I sleep with a CPAP machine. I do all these things to deal with my insomnia. I still have a difficult time going to sleep and staying asleep. I often only get 3 to 4 hours of sleep, which is insufficient. My second issue that contributes to my inability to get a good night's sleep and is disturbing during the day is pain in my left lower back, hip, leg, calf, and foot, which gets worse at night. Sometimes, my right side does the same thing. I have tried physical therapy, chiropractic sessions, rolfing, somatic therapy, massage, acupuncture, stretching, and pills. I am still in pain quite often. Can you help me deal with these two situations? Peace, Ray

Proctology

Not for an AMA, but a topic that may be covered by an expert guest: things that can go wrong with the very end of our digestive system. A topic that makes people seriously anxious, even depressed, yet rarely is shared with family, friends, even doctors. Hemorrhoids, fissures, fistulas, itching, pain, bleeding, prolapsed mucosa, skin tags... causes, effect of stress on the development of aggravation, prevention, DIY remedies, medical procedures, risks and benefits... Thanks for considering!

Adderall and sleep

How does Adderall affect our ability to access deep and REM sleep? Does vitamin C eliminate it from our bodies?

How to use what we know about eyeballs and any other body responses/reflexes to the stimulus of an attack to a person?

Since as you had said that eyes are each a "brain", how do I use that knowledge in self-protection or martial arts combat? Would that mean I can respond to a sudden attack faster than if the eyes are not each a "brain"? What about the flinch reflex? Is the flinch reflex any faster for a visual stimulus than for an auditory stumulus, as the research on the flinch reflex commonly applies to an auditory stimulus? Does the flinch reflex always come from electrical signals coming from the same place -- the brainstem? In any case, what if anything is different between the physiological and mental response to different pathways of stimuli, whether they be auditory, visual, or any other venues of stimuli that illicit a response to an attack to a person?
