Anyone who’s had an adult that is aging in life, or has seen a parent decline in health, thinks about long term care at that point. The average age for a person to purchase Long Term Care Insurance is between 50 and 55. But the shocking truth is you could purchase it all the way up to age 74. The most important thing to keep in mind is that when you get this type of insurance, it’s cheaper when you’re younger, so the sooner is better.
