This is true, but depending on the individual it can also mean that one might need to be good at drawing a line and stopping at it. I do sometimes work late when chewing on a more difficult problem, but if I don't stop early enough to leave a decent gap between end of work and bedtime, it can sometimes be difficult to get my head turned off and get to sleep. I miss my teens and early twenties when I could flop into bed and fall asleep no matter what I had been doing prior.
