Oh fuck, this question kills me. I have a very intense fear of losing control of my memories, so this hits close to home.
I would give up my past memories. It’s only ~24 years worth of life. I hope that I have a good long life ahead of me that will be well over double what I have already experienced. On with the good ones. My family and significant other can fill me in on most of what I have forgotten.
Although remembering my passwords would suck. Maybe I should make a document..
