ns waiver notwithstanding, years training for olympic level sports are way more shiong and harsher in personal sacrifice than ns, which is now a cakewalk. it requires a lifetime of training, pain, injuries, recoveries, mental conditioning to qualify for the olympics. getting a medal is a bonus. schooling, imo, has already served over 20 years of ns, starting from the day he learns how to swim competitively. there’s no need for a waiver. sg owes him.
