As Trump turns 80, what's it really like to work as an octogenarian?

In February, Arthur Rose stepped into his office as an internist doctor for the last time after practising medicine for over 65 years.

His retirement was a birthday gift to himself on his 95th birthday, partially inspired by his brother who passed away at 95 during the Covid pandemic.

"The job was really not pleasing me anymore," he said. "I just wasn't getting that same kind of exhilaration."

Rose, a Michigan native, is part of a growing population of Americans who are working well past the typical age of retirement, which in the US is 67.

Chief among them is President Donald Trump who is turning 80 on Sunday, making him the second oldest leader of the US behind Joe Biden, who left office aged 82. Trump is also one of the oldest world leaders, according to Pew Research Center data.

The percentage of those 65 and older who are in the US workforce has quadrupled since the mid-1980s, according to Pew, with about 19% of the age group holding a job.

They work in a range of positions, including high-powered jobs like lawmakers, presidents and company executives. This year, 24 members of Congress were older than 80, including Senator Chuck Grassley, the oldest lawmaker at age 92.

Several factors may be leading more people to work into their later years, ageing experts said. For one, more people have access to health care, meaning more Americans are making it to their 80s.
