Do you remember when we used to go to football matches and gigs and if someone scored or if the band played a particular banger we’d hug each other and jump up and down? 

It's nice to let your mind wander back like that at the moment. But equally, you will likely have a very vivid memory of this pandemic 10 years from now. Memories aren’t always nice... or even helpful.

So what if we could erase the ones we don’t want? Could it be possible and would we do it?
