The Ministry of National Development has officially declared that the pectorals of 74-year-old Tan Ah Kow are now more structurally sound than the HDB block he inhabits.

These "Pull-up Uncles," who spend sixteen hours a day defying gravity at void deck exercise corners, have evolved into a sub-species immune to arthritis and public decency laws.

Armed with nothing but sweat-stained white singlets, these senior citizens are reportedly capable of crushing coconuts with their glutes while complaining about the price of eggs.

“Aiya, young people now all strawberry, carry phone only already hand pain,” said Mr Tan while performing a one-armed planche on a rusty yellow bar.

“I just lepak here do some small exercise, then go coffee shop talk cock, no need pay gym membership to look like soft char siew.”

Scientists believe their superhuman strength is derived from a diet of thick kopi and pure, unadulterated spite toward the younger generation.

The government is now considering using these shirtless octogenarians to power the national grid via giant human-sized hamster wheels.
