I have been paying a life insurance since 2009 at 3.5k for a coverage of 100k for death, total permanent disability and 36 types of illnesses.
now the coverage has increased to 120k.This sounds like a traditional critical illness policy. The coverage increases as you age and your premiums should participate in the company's p&l, sharing into its dividend payments (to you) on top of some basic cash value, and some terminal bonuses to be accumulated throughout the years.
Myvi is a compact car, so is suzuki swift, and Mercedes A series. They all serve the same purpose.
However, the price difference is huge! How is it that we still see Mercedes A series around?
They all come with different features and unlike the Myvi, the Merc A commands some attention in different departments (compensating perhaps?

)
Your 2009 policy is a Merc A.
The one your friend bought might be a suzuki swift (most probably ILP).
It comes back to the question: what is your financial goals, and what is your objective to buy an insurance policy?
The features in every type of policy differs. It is not the question whether the policy is "good enough" but rather how well the features and benefits of the policy complements your goals and objectives!
You are the captain of your boat. Are the sails catching the wind at the right angles and moving you in the direction that you are going?
Well said... U made a point here
