Clocks Go Forward

Yesterday we had to change the clock at 3:00 AM. From 3:000 AM to 2:00 AM.

There are several studies which say that this clock change will influence in our behaviour because we'll have less sunny hours.

I don´t get to understand these hypothesis since I think I don´t feel affected by this changes. It's true that I´m lazier during Winter than in Summer because we have more dark-hours and more cold!! But despite of that, my behaviour is the same one. We feel waker because of the weather, not because of the clock change!
