Everyone says that about themselves. But, put yourself in your wife's shoes. She would want to do the best for you and would also want to live comfortably as well. Everyone always says they will sell their house and use that money. What if the market is like it is now with housing when you die. You will leave your wife with bills she can't pay, stress, no time to mourn b/c she has to worry about bills, etc.
Can you tell I have my Life insurance license, Series 6 and Series 63? I would offer to be your agent, but I am not beating the streets at this point.
Edit: Also, beware of your work insurance. You can take it with you (term) but at a much higher rate than normal. What if you are laid off? It is better to have a little at work (usually low cost) and buy some on your own.
