Conspiracy theory. Rewinding age legally.

What if I have an offer to rewind my age? Let say, 7 years. For a small fee of RM300, perhaps the glitch of a switch to tweak the MyKAD database binary bits and voila! I am now seven years younger. Would I sanely take it up? What about you? I do know someone, whom didn't know I do, that he is not what his age states in his identity card. For the person-who-shall-not-be-name, is in fact 2-4 year older than official document states. Heck, even my ex-girlfriend's date of birth isn't really hers.

Looks can be deceiving they say. I may look 30 but actually 23 only or vice versa. What benefit lies in rewinding official age back 7 years?

1) Insurance premium cheaper.
2) Less candles on birthday cake.
3) Feel younger? (assume I ensure good healthy life)

Momentarily, can't think of anything else besides the first item above. What about earning power? Would employers take age into account for renumeration? If yes, why must they exploit of a person's age? Take for example, 2 candidates go interview. One (real)30 y.o vs (fake)23 y.o programmer. Same qualification, same 3 years experience in that field and communicates almost the same maturity. I am almost convince management would hire (fake) 23 year old programmer, instead of 30 y.o.

What reasons you think management would bring up to justify that?
