50-year-old Tess Christian has a remarkably wrinkle-free face, and she told the UK’s Daily Mail it’s because, as a kid, she trained herself not to laugh or smile. While over the years looking bored became an anti-aging technique, according to Tess it didn’t start that way. She blames the strict catholic school she attended as a child, where the nuns told her not to smile. Over the years the strategy has paid off, as she has almost zero lines on her face and she has the pictures to prove it!
