From recent world wide medical/scientific data, it is very obvious that there are two main root causes of aging.

The main one is inflammations in the digestive system. The other one is an imbalance of chemicals, also largely in the digestive system.

The inflammations are often un-noticed and un-treated until they become chronic.Then it is medication or operation.

The cause of the inflammations are usually an excess of viruses and bacteria, of which there seem to be a world wide increase in all countries. The resulting infections become too much for the immune system to handle, so chronic inflammations result. The digestive system is then unable to produce sufficient of all the necessary chemicals, both for the immune system, and other vital organs - and so health meltdown begins.

I had a very recent first hand example of this - my mother was dosed with megalitres of antibiotics to contain a lung infection. She had very wrinkled skin, which soon went very smooth - indicating that much of her digestive inflammations must have been eradicated.

Author's Bio: 

Self funded health researcher. Therapist in own pain relief clinic, using essential oils, including rare ones. Research and testing over last 7 years in brainwaves - resulting in final CD of smooth flowing music and layers of each brainwave frequency - that balances brainwaves. Health benefits are numerous - including adhd, dyslexia, deep sleep, relaxation, attention/focus, and lateral thinking. Latest project is anti-aging - causes mostly inflammations in digestive system.
