Get married. You need some long term companionship.

If not buy a dog and die alone.

So better get married.....

Getting married is way better than dying alone.

To your question, how sure are you that getting married wont enrich your life as well.

We are social creatures. We are not designed to live alone. At the end years, 60's 70's, how many of your yumcha buddies will be around or lepak with you. Most of the time you'll be alone.

Anyway, being with someone, making your other half happy, has its own fulfillment.

Your shallow thinking deserves a lonely death. Have a good one.
