I can stay up late but I'm not productive. If I wake up at 5.30am I'm productive within 15 minutes and have a couple of hours before being bothered by family, co-workers etc. I must have a siesta however, and organise my life to allow this. I wish siesta was far more accepted above sleeping late or rising early.
