So focus on getting to know the person and try to enjoy the hike. Long term, the real beauty of any relationship (be it romantic, family, or something else) is having people you can like spending time with and can trust worth your celebrations and troubles.

Also, it’s not like most people can just walk into a lab and start cooking to cancer eating viruses. Just because I know someone did it doesn’t mean anything to me if I found out I have cancer tomorrow.
