It was discovered that the body would respond the same way as experiencing hypoxia if we had a sudden change in oxygen levels (a fluctuation), bringing the oxygen level up and back down. Bringing the level from high to low is being interpreted by the body as hypoxia.

Increasing pressure allows more oxygen to enter lungs. If we increase pressure and then decrease pressure to normal levels, it was descoverd discovered to trigger the same response as hypoxia which triggers your body to create/stimulate stem cells.

We can enhance our own innate defences against disease by: 

• don't smoke
• eat less often, skip a meal
• become exhausted from running (become hypoxic)
• lifting weights
• eating the right foods - olive oil, wine, organic food, stressed food, less or no meat.

You can increase your NAD(??) levels by

• eating less often 
• fasting

If there is one thing you can do in mid life that can increase your NAD levels it would be fasting.

It is no so much about what you eat or how much you eat, it is more about when you eat. Don't always give in to those hunger pains. There are some bodily processes that only function when you are hungry (Autophagy). Autophagy is the body's way of cleaning out damaged cells, in order to regenerate newer, healthier cells.

Conclusions

In the short term, we should look at changing our lifestyle until a time when we can reverse aging with treatment.
