1 . When I started secondary school, aged 11, I found myself in a class with only two children I’d met before.     1    . In fact, before the end of the day one I knew all 28 of my new classmates by heart. Even in my thirties, when I found myself back in school as a teacher, I could still learn all the students in my classes with relative ease. Here are three quick memory techniques that help me.

    2    . Remembering people starts with listening to what they’re called, and taking a proper look at their face. I make a point of repeating their names in my head, and silently saying something to myself about their appearance.

Spot similarities.     3    . So, who does this person look like? Do they share a name with a celebrity? Is there anything about them that reminds you of places, events, or experiences you’ve already got filed away?

2 . It’s normal to wake up at night, especially as you age, but negative news can further activate your mind and make it hard for you to fall back asleep. Therefore, hope the following tips can help you have a deep sleep.

Test your pillow.     1    . The National Sleep Foundation recommends replacing it every One to two years. A pillow past its prime can cause neck pain—and restless sleep.

    3    . If you need to complain with your wife or husband, don’t wait until night. Tough discussions are less likely to influence your sleep if you start them earlier. Arguments can activate your sympathetic nervous system, which affects sleep. Some research even suggests that going to bed with anger may make you impatient the next morning.
