I did the same thing for the same reason with the same result and am just posting this to concur with what you said: everyone should do this while you are young and have your memory.
Which makes me thing: we are relatively young and have our memories (again, relatively) intact. Should we be recording ourselves for our kids?
If you don’t have kids or nieces/nephews, but think you might, should you do the same?
With phones, are we recording ourselves anyway and won’t have to worry about this?
