Trump's health and age: a controversial issue in the campaign.

Donald Trump, who is 78 years old, might be the oldest person to become president if he wins the election. He hasn't shared much information about his health, which is different from what other people running for president usually do.

There have been a few times we learned a little about Trump's health, like when he got hurt or had a doctor's note. But we don't know important things like his weight, blood pressure, or if he has any health problems.

Kamala Harris, who is running against Trump, says it's strange that he won't share more about his health. She thinks people might worry if he's strong enough to be president when he's so old.

Harris shared a letter from her doctor that gives lots of details about her health, like that she's in good shape and takes allergy medicine. She wants Trump to share similar information so people know he's healthy enough to be president.

Some people who don't like Trump are making ads about how old he is, but it's not clear if voters care that much. It's a bit strange because Trump used to say that Biden, who is also older, was too old to be president.
