There is no perfect age to get Life Insurance. Certain major life events such as buying a home or having a child is a good time to look at personal insurance coverage.
A good way to think about when to get Life Insurance is if someone you care about would be affected financially if you were no longer around. As premiums are based on age and health, the risk of waiting is that you may have a change in health and could become uninsurable in the eyes of an insurer. Premiums will also be more expensive as you age.
