Getting found out is a legit problem if such thing were illegal, but just assume that your memories with your clone will be synced at the end of each day, and everyone who you want to know about your clones is cool with it.
I'm gonna entertain your idea and say if i have to make a cloan (because if there is a choice i wouldn't) i'll give us 2 minutes before fighting to death (if you have seem invincible series they kinda explains the clone dillema )
I don't understand the number of people in this thread who can't seem to enjoy their own company. Hell, I'm sad and depressed too when I'm alone, but I manage to get the laundry done and keep the lights on.
