Our lifetimes are limited! It can be attributed to our unstable DNA structures. Our genetic material, deoxyribonucleic acid, abbreviated as DNA, are prone to attacks from our own bodies and our external environments. If the DNA inside a cell is damaged, the cell will not be able to function properly and will probably die. Our bodies’ functionality will gradually decrease and would not be recovered if
new healthy cells are unable to regenerate to replace the dead or non-functioning cells.
The even worse situation is that the cells with DNA damaged are transformed into malignant cells, i.e. cancer cells.
Cancer is one of the major killers for the elderly. There are a vast of cancer type: breast cancer, liver cancer, pancreas cancer, brain cancer, colon cancer, skin cancer, etc.
To reduce our rate of suffering cancer, it is very important to avoid DNA damages. The ultraviolet light from sunshine in noon can damage DNA for skin and cause skin cancer. It had better to avoid sunbathing in the noon without any protection. It has long been suspected that cell phone usage and other use of electronics that emit electromagnetic radiations can increase the rate of suffering brain cancer and other types of cancers. Therefore, it had better to reduce these usage as much as possible. Buying a cell phone that emit less EMF, avoiding chatting with cell phone for too long may be helpful for you. There are some EMF protection jeweleries on the market and you can easily find them by surfing the internet. An example of them is VitaGuard Inc. and you can find it by typing VitaGuard in Google.
I hope that these information is useful to you.
