Question

Can humans live for 200 years?

Answer 1

Human life span:

1. Humans' life expectancy (average) is 70-85 years.
2. However, the oldest verified person (Jeanne Clement, 1875-1997) lived up to 122 years.
3. As a person ages, the telomeres (chromosome ends) tend to become shorter in every consecutive cycle of replication.
4. Also, bones start getting weaker by reducing in size and density.
5. In addition to this when a person starts getting old, muscles become less flexible (results in poor coordination and balance).
6. These are natural changes that occur while aging. They cannot be stopped but it is possible to slow the rate of these processes.
7. This can be done by changing one's lifestyle (diet, exercise, etc).
8. The science of aging is not yet fully understood; therefore, it is difficult to determine an absolute limit of 200 years.
