IMO, SAF Aviva is worth to keep. Of course my opinion might not worth anything also haha.
DPS NTUC, all CPF members will automatically be enrolled. Is only $36, and is deducted from your CPF, just put it lah. Think about is $36/year after 40 years how much only (though I know the premium will increase with age, but i think $46k is still better than what u paid).
Anyway DPS, is for your kins. When you "move on to another place", they can use the money to give u a grand funeral, thats what I told my friends haha
34 and below $36
35-39 $48
40-44 $84
45-49 $144
50-54 $228
55-59 $260
Total add up, I doubt got $46k
Just treat it as a term insurance that covers u till 60.
