Most probably two to four different dudes.

1. The $5m guy with $350k pa savings who also advocated working as long as you can
2. The 57/58 yo retired couple
3. The young retired successful ex-exec who made it good and now doing charitable work
4. The dude who gave encouragement to everyone who posted and urged them not to womanise, smoke, drink etc..

Then there are the others who advocated renting out the HDB andliving in M'sia, Thai etc

And now we have a persistent car dealer.
