Yes, I do. I have slept for three to four hours most of my life. I have never been sick, always been a top level athlete for my age, never broken a bone, blood levels always in optimal range. I also know a few people that have slept three hours a night for fifty or so years and died at 80 years old.
Being unhealthy leads to health problems, being able to function on a few hours of sleep doesn't cause health problems, but sleep depriving yourself may. However, I can point to personal friends and more well known people that do force themselves basically to be insomniacs and are healthy.
