sunlight

I never like the sun, if i'm given a choice, i would definately choose night over day at any day.

Why the heat transfer only from high to low naturally? Why cant it be both ways !?

The night is much better than the day, the most obvious reason? No sunlight.

For that? Lower room temperature.

Why human after so many centuries still stick to the norm? Why cant we make the night as or default working schooling time?

I can list out a few advantages.
1. No sunlight
2. Heat engines(eg. Car's engine) is more efficient the density of oxygen is higher in low temp
3. Reduce usage of air cond, green living. Cox? No sunlight that heats the air up.
4. Less friction, less energy loss. Reason? No sunlight heating up your work surfaces, surface area lesser, friction reduced.
5. ......
6. .........

Disadvantages?
1. Need to use more energy for man made light. Who cares? You don't need to light the whole town up to take a dump right? In fact its an adv for some too, their location for instant physical love have increased marginally, by the dark road, under the tree, etc etc.
