Yes, I think so too. Or a wonderful love story. I love seeing senior citizens who are married for sixty, seventy years or more.
Maybe Romeo and Juliet will be one of those couples and who will be married for sixty, seventy years, and when one of them dies from old age, the other one will have a heart attack and die a minute or so later from a broken heart.
Could be ... but it would probably still be a boring play, unless they solve murders or something ;-).
