Lifelong is a term used to describe the ability of an organism to live for an extended period of time. In humans, the definition of lifelong is typically used to describe someone who lives to be at least 100 years old. However, there are some organisms that can live much longer than this. The oldest known human was 122 years old when she died. But the longest-lived animal on record is an Icelandic fish called the Greenland shark, which can live up to 400 years.
There are a number of factors that contribute to an organism’s lifespan. One of the most important is genetics. For example, certain species of animals have genes that allow them to live longer than others. Another factor is environment. Organisms that live in harsh environments often don’t live as long as those that live in more hospitable environments. Additionally, lifestyle choices can also play a role in lifespan. For instance, smoking has been shown to shorten lifespan by about 10 years on average while regular exercise has been shown to increase it by about three years.
While the vast majority of organisms don’t come close to living as long as humans or even Greenland sharks, there are a few exceptions. Some bacteria and other single-celled organisms can reproduce indefinitely if conditions are ideal and they don’t run into any predators or other dangers. Additionally, there are some plants like trees that can also live for hundreds or even thousands of years if they aren’t cut down or otherwise damaged
