Tourists, beware: Riding elephants isn't fun for the animals, and it could even kill them.
Bowing under the weight of a group of sightseers in Vietnam, a 40-year-old male elephant collapsed and died Sunday, Viet Nam News reported. The cause of death was reportedly "overwork," though no official autopsy was conducted. In the wild Asian elephants can live up to 60 years old or more.
This is the second high-profile elephant death in the same region lately: In January, a 36-year-old "tamed" elephant was found dead, reportedly from exhaustion. There are some 50 trained elephants working in this particular tourist region in southern Vietnam, and travelers there pay to be ferried around on the pachyderms' backs.
