Does taking a life insurance policy help ?? at my age ??

Im only 27 & this person introduced me a Life Insurance Policy (LIC) where il get the benefits only after 15 years & i pay them for 5 years in installments, where in it will benefit only after 15 years. It wud cover up even any accidential causes too. Shooud i go ahead with this policy ?? My first experience, as a single man. Im thinking if its worth investing in this or not. People who are aware of this already can advice please.
