Age is just a number. Malaysia's ex-leader Mahathir Mohamad, 97, is proving this. He is rolling back the years and running for office again. He has been the country's leader twice before. The first time was for 22 years, between 1981 and 2003. He did not tell journalists whether or not he wants the top job again. He said: "We have not decided who will be prime minister because the prime minister candidate is only relevant if we win."

Mahathir Mohamad became a member of parliament in 1964. He is thought of as being a visionary for greatly improving his country's economy throughout the 1980s. His run for parliament is his 11th election campaign. Many have their doubts about his chances of success because of his recent ill health. He has had several heart attacks and had quadruple bypass surgery. He left hospital last month after contracting Covid-19.
