David... ur heavier then me >.> seriously... check ur weight lol

simple mathematics would prove that u are more then two times heavier then me; Allow me to show u... Since David believes that i weight more then him... let us make...

David < k2a
David/2 < ka
Dvid/2 < k __________ Let k= keean's weight where this equals his weight of 64kg
Dvid/2 < 64kg
Dvid < 128 kg ____But Since Dvid is short for David... Therefore David is greater than 128kg

Simple arithmetic proves this... thank you

I shall leave you to ponder on this
