英文摘要：

Molecular biology research makes the human understanding of aging from whole animal level advance to the cellu lar level and molecular level. The study of DNA methylation and aging is one of the hot points in the field of life science. There are so much philosophic thinking in DNA methylation and aging, such as the opinion of microcosmic and macroscop ic.
