to some degree thats my point for most jobs either

- you don't care about the clock but some time relative to sunrise

- aren't dependent on sunlight on your job anymore

- anyway have to head out very early before sunrise (for most of the year)

sure maybe DST does save a small bit of electric bill in some jobs, but thanks to modern light technology it's not really that relevant anymore, on the other hand the reliable increase in traffic accidents every time we switch to summer time does matter.

Now there still is the argument about what is healthier (ignoring the known unhealthy switching times) but there is so much with way stronger effects in modern life (e.g. TVs, bright white LED lamps etc.) that I'm not sure if the effect if even realistically measurable.
