On 4 July 2014, conjoined twins Ronnie and Donnie Galyon (USA, b. 25 October 1951) were 62 years 252 days old, surpassing their heroes Chang and Eng Bunker (b. 11 May 1911, d. 17 January 1874), the world-famous conjoined twins, who had lived to be 62 years 251 days old. When Ronnie and Donnie turned 63 on 25 October 2014, they then matched, or even surpassed, the twins recognized as the oldest conjoined twins ever, Giacomo and Giovanni Battista Tocci (Italy, b. 1875), who were widely reported to have lived 63 years.
