"All that's left are memories"

This is what many elderly people say when they mean that all the fun and meaningful time of their lives has already been spent. Now they can only watch TV or look outside the windows for hours without end. Or emotionally abuse all the people around them spreading all negativity they have accumulated like a virus. Or keep doing physically exhausting work as long as they can without any joy.

But this isn't true, is it?

All they need to do is to go collect some new memories.
