Life long Porphyria sufferer here, a hallmark symptom is Insomnia. I've lived on 6 or less hours of sleep all my life, the only time I sleep longer is during a bad porphyria "attack", then it's like 19 hours at a time, but that's only several times a year. Subsequently, my career choices accommodated it, I became an entrepreneur so I could set my own hours (like after Noon), and a 40 year career doing late night broadcast radio. I've seen these "studies" so many times, all I can do is Laugh, oh, and keep on Living this way, and I've made it to 65, and still going, so hooey on those "studies".
