If they don't change the clocks there is nothing to "feel".

Gaining an hour in the spring is usually fairly benign, changing the clocks is experienced the most when we loose and hour in the fall.
Either way I don't think it is healthy and only partly beneficial at more northern latitudes.

In California I used to get intense episodes of spring fever. not so much here, but that could be part of what I am experiencing.

"The first human clock mutation was identified in an extended Utah family by Chris Jones, and genetically characterized by Ying-Hui Fu and Louis Ptacek. Affected individuals are extreme 'morning larks' with 4-hour advanced sleep and other rhythms. This form of familial advanced sleep phase syndrome is caused by a single amino acid change, S662➔G, in the human PER2 protein."

I have always resonated with being a mutant
