It is a kind of accepted resignation that one's reaction time may slow with age, memories of recent events may not be as sharp (while surprisingly memories of thing long past may stay vivid in the mind), they may be physical degeneration and medical problems like high blood pressure, heart (cardiovascular) diseases, diabetes, osteoporosis, etc., may start to set in. However, not everyone may age at the same rate.
The human brain, a three pound slab of soft matters, is a really remarkable organ, perhaps even a miracle. Structurally, the human brain comprises of 2 parts, the left brain and the right brain. The anatomist may divide the brain into three parts: the fore-brain, mid-brain, and hind-brain.

"In Full Bloom" claims that while it is true that genetic heritage can affect the way our brain age, it is only fifteen to thirty percent.

Mr. Ilchi Lee is Korean, and there is a Korean word "jangsaeng" which can translates as "longevity". However, there is a deeper meaning to the word than just longevity as that is merely a passage of time with no indication of your state of health. The Korean word "jangsaeng" also means living long with a youthful vitality which his book wants to help promote.
