Your liver is just under three years old

The liver has a unique ability to regenerate after damage. However, it was unknown whether this ability decreases as we age. Scientists have now used a technique known as retrospective radiocarbon birth dating to determine the age of the human liver. They showed that no matter the person's age, the liver is always on average less than three years old. The results demonstrate that aging does not influence liver renewal, making the liver an organ that generally replaces its cells equally well in young and old people.

Too much self-confidence can endanger health

Older people who overestimate their health go to the doctor less often. This can have serious consequences for their health, for example, when illnesses are detected too late. By contrast, people who think they are sicker than they actually are visit the doctor more often. This is what a new study based on data from over 80,000 Europeans aged 50 and older found.
