Chemotherapy and radiation treatments are part of it.
I've also got blown discs in my back, 2 bad knees and I bad hip.
Between playing competitive mens tackle football, basketball and softball, I've also wrecked numerous times while racing cars and motorcycles. I finally retired at 45. Way to much pain.
I'm also an aeronautical buff and have unfortunately crashed planes 6 times. Fortunately none were to awful.
I still fly numerous times a week. Just much safer aircraft. No more home built or experimental aircraft for me.
It was obvious when I was no more than a few years old that I was prone to accidents. I just sold my motorcycles just over two years ago, and cancelled my health insurance. I've also got two squished discs (L3 and L4), but I went to a doctor who instructed me to take the painkillers he was prescribing to me for one month, and to do some exercises to strengthen my back every day for that month, and that after a month, I would no longer need the pain killers to continue doing the back exercises. He was right. As long as I do these exercises, I have nothing to worry about.
During a trip down to Nogales, NM one winter, I noticed that all my aches and pains disappeared, and then magically reappeared a few days later while I was up in Seattle. I really didn't have a clue just how much pain I was in until I experienced a complete cessation of pain followed by it re-emerging up north.
Then I eliminated wheat, corn, flour, fruit juices, dates, raisins, bananas, white rice, sugar, etc. from my diet, and proceeded to lose 150 lbs. in seven months. That's just from eliminating sugar from my diet. After having a standing diagnoses of congestive heart failure for over 15 years, my cardiologist, with a look of dumbfounded amazement; informed me that I no longer had congestive heart failure. This was only six months after my last office visit. I haven't seen any doctors in three years now, and don't plan on every seeing one ever again.
I've had well over a pound of flesh removed along with the cancers it surrounded. I've also watched way too many people die from chemo and radiation. There is no way I would ever subject myself to that nonsense, and at this point, there's no reason why any doctor would ever suggest it anymore. I'm cancer free, and will probably be cancer free for the rest of my life because my body is well oxygenated (cancer can't live in an oxygenated environment), and sugar free (cancer LOVES sugar).
I can also get significantly more stoned out of my mind just by eating a bowl of cornflakes, a slice of pizza, or even a few slices of watermelon than anything bought at a dispensary.
What I've discovered is that even though I don't eat any of that stuff anymore, I can wake up stoned out of my mind anyways. I'm literally high on life itself. I'm probably in better shape now than I was 30 years ago, and that's with all the broken bones, stitches, etc.
The body is incredibly resilient, and can completely recover if given half a chance. There's an incredible documentary by a woman named Nancy Appleton, titled "Sweet Suicide". There's a scene down in Papua New Guinea where they're looking at a tribe that has no outside contact with the rest of the world. No one in the tribe has any of the degenerative diseases that plague so many people in first world countries. The documentary shows these people in their 80's and 90's looking like they're in their 30's. They're happy, healthy, and ripped!
