At what age do you think Filipino couples should start thinking about starting a family?

I've discussed this with friends of many nationalities and I find that Filipinos' views on marriage and family are the most similar to my culture (Malay). Ideally, we hope to marry in our twenties but these days, alot of us end up marrying closer to our late 20s or early 30s due to a variety of reasons (career, education, stability). At the end of the day, marriage should be something not taken lightly and not to be done out of trends or just because everyone is doing it. As much as it is a matter of the heart, one should proceed with his or head as well.
