Mother Shani Clarke, of Perth, Australia, had warned her 35-year-old son Michael against drinking too many energy drinks. She noticed him carrying an armful of cans out of his truck one day and told him that too many of the drinks could be harmful to his health.What she didn’t realize, though, was that he had been consuming as many as four cans of Mother each day. The popular energy drink in Australia and New Zealand contains 160 mg of caffeine per can; that’s over two-thirds more caffeine than 1 normal cup of coffee.
