Are you a 28-year-old woman? Enjoy it. You're the happiest you're ever going to be, according to a survey of 4,000 women. "The age of 28 has been pinpointed as the time in a woman's life their hair looks the best, body shape is at its peak and confidence is at an all-time high. The security of your job, having a steady income, being in a relationship and having strong friendships all help create the perfect point in our lives when everything comes together." Then it all goes downhill, naturally. "By the time they have turned 30 they start worrying about growing old and developing grey hair and wrinkles." That line about grey hair? It probably isn't accidental. The study was commissioned by Clairol. [Telegraph]
