The scenario is that by magical technology a scientist is willing to pay you to wipe your memory, but his device has enough fidelity to wipe one day at a time counting backwards (so you can’t wipe all memories at age 15 for example).
The scientist is capable of doing what he says he can do, he has no malign motives apart from his odd interest in studying human memory and there are no other unwanted side effects or dangers to the process, the lost memory also cannot be recovered by any means, its gone permanently.
He is willing to pay you at a rate of $250 per day, so wiping 30 days of memory you get $7500 in your hand, five years and its $465’000 and so on. He is a very rich man so there is no concern that you won’t get paid.
So how far back would you let him wipe your memory? Or would you let him do it at all?
