The length of time that a living organism is expected to survive, often considered to be predetermined or influenced by inherent factors.
The duration for which an object or device is expected to function effectively before it is deemed no longer usable or safe.
The specific period during which subatomic particles, atomic nuclei, or molecules remain in a particular state before transitioning to another condition, commonly referring to their average duration in such a state.
Example:
これらの発見のおかげで人間の寿命が以前の２倍になった。
A statistical measure that indicates the average number of years a newborn is expected to live, calculated from mortality rates at different ages within a specific population or country.
The expected duration of life for a group of individuals, often derived from life tables, reflecting the overall health and living conditions of that population.
The average lifespan of unstable particles or radioactive isotopes, expressed in terms of decay constants or half-lives, showcasing the time it takes for a quantity to reduce by half.
Example:
