Marry this man, if:
1. You want a life where you must be continually hypervigilant -- i.e, never let your guard down, EVER.
2. You don't want to have children, EVER. Children do not need either these genes or exposure to such a hypervigilant lifestyle.
3. You are aware that you are likely to bury this man at an early age. Statistically, you will be a young widow.
I'm sorry to be so blunt, but the odds are against you having a happy life with this guy.
