Such a firm and straightforward remark! It’s clear that loving your family comes first compared to other factors in life, for which I do admire you! Just remember that the question is not directly related to your connection with your family, but your life expectancy or longevity.
In other words, it concerns the quantity of life as opposed to its quality. People could have a pretty short life but stay so close and intimate to their family members, and also vice versa. You also mentioned “as long as possible”, and from that vantage point, it’s clear that you like to be in close touch with your family members as long as possible.
