The other day, I asked Mark Mastrov, co-founder of New Evolution Fitness Co., a favor for an upcoming story. He said he'd get back to me in 24 hours. When reminded that "24 hours" had a familiar ring to it, Mastrov, the founder of 24 Hour Fitness, said it was just a habit and added he'd get back to me in 25 hours.
Some habits really are hard to break.
