The nuceli is ejected after the cell is formed. This affects not the life span, but the ability to make energy. The life span of a red blood cell is 120 days.

A sickled red blood cell will live for 10 to 20 days before it is destroyed. A normal red blood cell would have lived for about 120 days. This is the cause of the anaemia in sickle cell anaemia patients, who typically live for about 45 years.
The human blood cell on average lives for apx. 120 days. once it dies it has to be replaced.
