I recently had to go check mine. Most of the time procrastination leads to the challenges of incompatible genotypes. When spouses failed to check out their genotypes before venturing into relationship, the become too bounded to each other and try by all means to force the relationship to work out after finding out their respective genotypes are incompatible for each other.
It's best to check ones genotype even before going into any relationship to avoid emotional, psychological and resources damage..
