Would you choose short love at at 20 years old or life long love at 45 years old?

I have a hypothetical that a good friend once asked me. Got me thinking and I actually couldn’t answer the question honestly – so I figured it would be interesting to see ya’ll flutherites’ reactions.

Someone gave you the magic wand of fate – You’re faced with the decision of finding the love of your life at age 20 (or in your 20’s) or when you’re 45. Which one?

There’s a catch! If you choose to fall in helpless, inconvenient, complete and utter, head-over-heels love when you’re 20, your partner has a fatal disease and will die in only 7 years and you will never love again. If you hold off until you’re 45, you and your partner will live together happily ever after. Which and why?
