Is life expectancy determined at birth?

Answer 1

No life expectancy is not determined at birth. Life expectancy is determined by a variety of factors. Factors that influence life expectancy are quality of life, health factors, environment, location, family life among others.

Exercise and eating habits influence our life expectancy, smoking and alcohol as well as illegal (and legal) drug use (abuse) can lead to a lower life expectancy. Health care and technology will generally improve throughout peoples' lives leading to an increase in life expectancy.

Answer 2

This would depend on many factors such as what country you are living in. For instance in Canada, the life expectancy is approximately 76 years. But if you were living in a poor undeveloped country, then the life expectancy would be less.
