"I'm still alive!" On the local time of the 20th day, Fred Mack from Pennsylvania, America, parachuted from a height of 13,000 feet (about 3962.4 meters) and landed safely. He celebrated his 100-year-old birthday in this way.
According to reports, Mack first attempted this sport when he was 95 years old and promised to parachute again on his 100-year-old birthday.
People can't help but envy his physical condition at such an advanced age that he could attempt extreme sports. Dr. Elliot Gober, Mack's cardiologist, successfully applied for the Guinness World Records for this centenarian before. He said: "Mack has been my patient for 20 years. His body is amazing, simply incredible."
