Imagine you wake up in the body of a famous and influential person in the bedroom where that person sleeps in. You know nothing about that individual prior to this incident apart from the fact that they are considered a high profile person.
Your only chance of survival here is to act like that person in front of their family, friends and the public for the rest of the unforeseeable future. How do you ensure you learn to imitate the personality of the individual by arousing the least amount of suspicion?
Honestly, unless it was a simple person or you happen to be somewhat alike to begin with… Not gonna happen.
People can’t change when their life or way of like depends on it, we see it all the time. And that needs far less drastically changes compared to being a different person altogether.
