Yes, a 64 year old can get life insurance, although the policy may be more expensive than for a younger person. Life insurance companies typically use mortality tables when setting premiums, and these tables take into account the fact that people of different ages have different life expectancies. So, all else being equal, a 64 year old will typically pay a higher premium than a 30 year old.
There are a number of factors that life insurance companies consider when setting premiums, including age, health, smoking status, occupation, and lifestyle. So, even though age is one of the primary factors, it is not the only factor that is considered.
If you are 64 years old and looking for life insurance, it is important to shop around and compare policies from different companies. You may also want to consider talking to a financial advisor to help you decide how much coverage you need and what type of policy is best for you.
