Depend, some family got wife working and kids go school, they
prefer to drive day, can take kids and wife to school and work. It
save them alots on transport, unless you are single or family
member work late or wife not working, then it should be ok,
however, night shift also got it good point, like no sun, less
traffic after 10pm, can park here and there, drive lesser and earn
more, and also can go jungle warfare once a while...

warefare.........

then go hm
hug the wife to sleep......... then morning can wake up send
kids to sch then
come back sleep afternoon wake up can see the kids again bfore
goin to work.
