Two thingspat:patdog said:no, don't do this. Buy term life if you need it (if you're single you don't need it, if you're married with no kids you may or may not need it) and invest the difference in premiums yourself. Also, buy disabilityinsurance whether you're single or married. Get one with a "your profession" definition of disability. Otherwise if you can still do any job you're not considered disabled even though you may not be able to earn anywhere near what you did before.
1. A whole life policy can be used as a retirement vehicle thatgrows tax free at a rateof around 5-6%. I know because I have one. However, I would not advise getting one if you have not fully funded your other retirement options (ie IRA, Roth, etc.) or if you don't have dependants.
2. If you have a family then you can get a million dollar term lifepolicy for around $70-$80 month which is a hell of alot more money when you die than investing it in stocks like someone said earlier.
