Take a look around your room right now. If you were to drop dead this instant would you be okay with having family members go through all of your stuff?
A lot of people have skeletons in their closet or on their hard drives that may be best left hidden even after death. It’s bad enough to have your friends and family mourn your passing but do they need the stress of learning you were into Japanese mud porn too?
So for the terminally ill, elderly, people wanting to maintain their double lives in perpetuity, and people living under constant fear of death, making arrangements with an experienced and independent 3rd party to come in and clean your space might be the way to go.
