A Singaporean man selflessly donated his kidney to his ill father who had less than one year to live and even forged the titanium stitchings from his father's operation into his own wedding ring.
The filial son, Shaun Nair, 29, told Shin Min Daily News that his father had diabetes.
Due to complications, Shaun's father started showing symptoms of kidney failure last year.
He went to see a doctor, who told him that he had between five to eight years to live.
However, when he visited a hospital for a checkup this year, he found that his condition had worsened, and an acute renal failure was imminent.
Shaun's father was told that he had less than one year to live.
The news came as a huge blow to him, who was unable to accept that he would have to undergo dialysis to live.
Shaun, a customer service officer, said: "My father thought for a while and told the family afterwards that he did not wish to for dialysis to affect his quality of life.
"He chose to give up on treatment."
At this point, Shuan knew that there were only two options for his father.
The first was dialysis, which he had rejected, leaving the only solution to be a kidney transplant.
However, after the family persuaded the elderly man to go for a transplant, they were told that he would be placed on a waiting list, and he would have to wait at least eight years.
To offer him a chance at life, Shaun decided to donate one of his kidneys to his father.
After a two to three-month intensive check, it was concluded that Shaun's kidney would be suitable for the transplant.
On July 2017, the father-and-son duo underwent a six-hour-long operation for the transplant.
Both resumed their normal lives after.
Shaun, who is getting married soon, added: "To commemorate this meaningful event, I decided to keep the titanium stitchings left from my father's operation.
"I initially intended just to keep it by my side, but later had the idea to forge them into a wedding ring which I'll wear every day."
