You want to die earlier? 
Wash with soap and water, immobilize the bitten area, cover the
area with a clean, cool compress or a moist dressing and monitor
your vital signs.
I don't know much about Singapore snakes, so whether seeking
medical attention is needed I'm not too sure.
If you feel giddy, nauseous, weakness, sweat excessively and
numbness, it's most likely you've been bitten by a poisonous snake.
Seek medical attention is the best.
