Is it because of old age? 80-year-old Trump's mouth has become more assertive and vulgar.

The New York Times analyzed on the 1st (local time) that U.S. President Donald Trump's public remarks are becoming increasingly vulgar, verbose, and illogical.

According to the NYT, when analyzing President Trump's remarks from 2015, when he first ran for president, to the present, he used categorical expressions such as 'always', 'never', and 'absolutely' 19% more than 10 years ago and 5% more than in 2024.

The NYT pointed out that this is a sign of black-and-white logical thinking that often appears as people age or their cognitive function declines.

Vulgar expressions also increased. President Trump uses about 15 profanities per 10,000 words, compared to 14 two years ago and 6 10 years ago.

It is also noticeable that the speech has become verbose and rambling. Compared to the 2016 presidential campaign, the number of gibberish or incomprehensible speeches during the second term was 2.5 times higher.

The speech time has increased significantly from 42 minutes 10 years ago to 85 minutes now.

President Trump's vocabulary and speaking level were similar to before, at the level of a 4th or 5th grade elementary school student. The speaking level of U.S. presidents is generally that of a second year middle school student.

The official schedule was reduced to 1.3 times per day compared to the average of 2.1 times during the first term. Posts on social media average 21 times a day, up from 13 in 2016 and down from 34 two years ago.

President Trump, who tends to be a 'night owl' who sleeps late at night, posted posts between 12 PM and 5 AM about three out of ten days in his second term. There were 240 instances where more than 10 posts were posted in an hour.

Recently, President Trump has repeatedly made inappropriate remarks and made personal attacks without hesitation in public, raising concerns that his self-control may have further deteriorated.

At a campaign rally for the midterm elections, he repeatedly made comments praising the Republican candidate's buttocks, while also yelling at a reporter who asked a question he didn't like, calling him crazy and telling him to be quiet.

The NYT pointed out, “President Trump has repeatedly shown incomprehensible behavior at national campaigns and the White House this fall, raising questions about his age and (mental) stability again.”

President Trump turns 80 this year. He was 78 years old when he returned to power early last year, making him the oldest U.S. president at the time of his inauguration, and has been the subject of ridicule for former President Joe Biden's declining cognitive abilities.

The White House dismissed concerns that President Trump is not the same as he used to be. White House press secretary Davis Engle said that President Trump is showing sharp judgment and unparalleled energy, and emphasized, "The American people love the President's unaffected and transparent appearance."
