Older people tend to be more forgetful. It's common for memory to decline with age, and some might even face health issues like dementia or Alzheimer's, which can severely affect memory. Also, older individuals often have a lot on their minds, like managing health or family matters, which can lead to forgetfulness. Sometimes, the medications they take for other health issues can also impact their memory.

Busy people are often forgetful because they have so much going on. They're juggling multiple tasks and responsibilities, which can make it hard to remember everything. High stress levels can also affect their memory. They might focus more on getting things done rather than remembering details, and their tight schedules can lead to overlooking things.

Young people can be forgetful too. They might not have much experience in organizing tasks or using memory techniques. Plus, they're often distracted by technology and social media, which can make it hard to focus. Young people also tend to focus on immediate gratification, so they might not pay attention to details that seem less important.
