If they're over 40 and haven't seen the truth by now, there's no point in converting them. They will always be the follower of 'the science,' which means whatever they're told is the majority opinion. These people feel safe in numbers, that's why they think the city is safer than the country. No matter how much it hurts to give up on your family and friends, don't let them take your life energy. Don't fix them, replace them.
