Yeah, so far there were just estimations. Even this is still in a wayI mean my gf's father has a twin and they were mirror image of each other but then in less than 5 years both became so different that you can hardly even tell that they are related in any way. If there will be few more twins to repeat this project then a more generic result could be gathered.
Most of the people that I hear complaining about it are old people and by that I mean people who are retired and time only tells them if it's the time for their favorite TV drama or medicine. IMHO daylight saving time helps both mentally (less gloomy dark winter) and energy-wise.
If I observe regular office hours, it's dark when I go to work, and it's dark again when I get out of work. One hour either way would make barely any difference. Don't see the point. And in the middle of the summer the sun raises around 4:00. So, yeah.
