Oh the oddities and mysteries of the human body never fail to fascinate and cause some to gag.
A young boy in Peru is due to have surgery as soon as today to remove his parasitic twin who’s own half-formed body is encased in the boy’s stomach. The eyes, some bones and even hair (!) remain of the fetus, but the brain, heart and lungs never formed. The fetus is about a pound and nine inches long.
This condition is rare, but happens in 1 out of every 500,000 births.
