Looking through different types of life insurance plans and getting life cover at 30 is a smart and practical idea. You get the benefits of buying life insurance at a relatively younger age, so currently, your premiums are the lowest they will ever be.
At this age, you are making more money than you used to, and you have a family or are planning one. Also, your health plays a significant role in how much premium you are required to pay. Since younger, healthier individuals present a low risk to the insurer, they are also offered lower rates. The smartest thing to do is lock in a reasonable rate when you are healthy and earning a professional income.
