Some of the advantages of marrying early are: you take on responsibility early and avoid reckless lifestyle, you have your kids early and all of you will grow old together, you experience the joy of martial bliss early, etc. It's always very cute seeing a 55 years dad or mum already having a grand child. Sometimes, when you see them walking with their own grown up kids, you would think that they're siblings. Marrying early has lots of benefits if you marry the right person.
