This is the remarkable moment a cyclist who has spent the last 12 years pedalling the globe to promote peace rattles off the list of 129 countries he has visited.
Lok Bandhu Karki stopped off in Hounslow on Friday (September 2) during the latest leg of his gruelling tour to spread his message of universal love.
He barely pauses for breath while listing the countries in this astonishing footage, captured by Meelan Sharma (@meelanepali).
Mr Karki was compelled by the civil war raging in his home country of Nepal to quit his job as a teacher in 2004 and set off on his incredible journey.
A dozen years and seven bikes later, he is nearing the end of his mission to cycle through 153 countries by 2017, spreading his message about peace and tolerance.
The 39-year-old, who describes himself as the "Cyclist for World Peace and Universal Brotherhood", has campaigned for an end to violence and hatred in an effort to leave behind a better world in his cycle tracks.
Met Nelson Mandela and been chased by elephants
Along the way, he has met leading statesmen and women, including the late Nelson Mandela and former UN secretary-general Kofi Annan.
He has also come under attack from a herd of angry elephants in Laos, been chased by gorillas in Uganda and felt the wrath of an angry mob in Sudan, who reportedly took offence to his flying the flag of a dissident political faction.
Mr Karki was hosted by Hounslow mayor Ajmer Grewal during his visit to the borough, which is home to a large community of Gurkhas hailing from Nepal.
"Although I'm doing my world tour to promote the message of peace and humanity, I do not want to claim that my tour by bicycle definitely brings or establishes peace in the world and globally strengthens humanity among the people of the earth," he said.
"But I believe it surely gives a kind of symbolic and spiritual message about the necessity of tolerance and value of peace in the world and encourage the young generation and other people to do something for peace and brotherhood."
'It's an honour to have him here'
Bishnu Gurung, who in 2014 became Hounslow's first Gurkha councillor , said: "What he's done is incredible and it's an honour to have him here."
He said Mr Karki planned to rest up for a few days in Hounslow, giving him time to recuperate and to renew his visa, before flying to New Zealand on Monday (September 5) and getting back on the saddle.
