HOW OLD IS MY BODY REALLY?
BRAIN 1 DAY
As soon as we fall asleep, a detoxification process is set in motion within the brain. Neurons and glial cells are renewed. A lack of sleep leads to cell decay.
LUNGS 3,285 DAYS
The lungs are a pair of organs that we would sorely miss after just a few seconds. On average, we fill each lung with 5 to 6 liters of air 15 times per minute. The lungs themselves are renewed once every nine years— other respiratory structures like the trachea are renewed eight times a year.
SKIN 28 DAYS
Skin protects us from threats such as the sun’s deadly rays and blocks the entry of illness-inducing pathogens. While it does so, it is constantly being renewed. After 28 days all skin cells have been replaced with new ones.
BLADDER 60 DAYS
Toxins reach the bladder via the kidneys— the organ is a kind of bodily depot for hazardous waste. The cells of the urinary bladder are constantly being renewed, so the organ is effectively replaced in its entirety six times each year.
The regeneration machine inside us faces a major challenge each day: Our body depends on the complex interplay of all its parts in order to survive— for that reason, most of its functions cannot be dispensed with for even a second. At the same time, the cells of the associated organs and body parts must constantly be renewed. This is why most repair processes occur with the engine running.
STOMACH 1.8 DAYS
Not only are nutrients pre-digested in the stomach— infections are also fought here. The gastric juice has an extremely acidic ph value, which means the stomach is an environment where hardly any pathogen is able to survive. The stomach is constantly renewed. The pyloric orifice alone gets renewed 200 times a year.
LIVER 20 DAYS
No breaks: During the day the liver recycles and stores nutrients (valuable energy) and produces vital proteins and defensive substances. At night it recovers by detoxifying itself. At the same time it is being constantly renewed: up to 18 times per year.
