Right, you *might* be surrounded by family, but if you go without warning (which is preferable IMO), low chance you’ll have family around at that very moment. And either way, they can’t come with you.
Ideal is you’re 95, had the grandkids/great grandkids out at the country house, played with them, had a BBQ, went up to your room and just didn’t wake up the next morning. Died alone in bed after a full day with family.
