Why arn't more humans nocturnal?

Why aren't more humans like me nocturnal? I haven't been out doors during the daylight in 5 years.My life is just fine, I don't suffer from depression or lack of vitamin d.I am very healthly and I have great night vision and a strong sense of smell.Daylight is so depression and I feel is filled with material wants and needs.Everything at night is much more beautiful.Why do people live during the day? Makes no sense to me,because it's cooler at night plus I think the winter nights are very lovely.
