sleeping and swimming at the sane time

 If only we humans could sleep as well as animals. They somehow manage to catch z,s even when they'er on the move. for water animals who need to breath  air they have no choice they can't  just sink to the ocean floor while napping so dolphins let 1/2 of the brain sleep while the other half is awake  with one eye open. while the other half is awake  with one eye open. while  the left half sleep then eyee right eye is shot then vice versa.  seal also sleep this way leaving one flipper  ready to flap around  air  breathing water  animals need to solve other kinds of problems like otters who tie their tails around seaweed to keep from floating away while they nap. and albatrosses can actually sleep while flying. You really have to wonder  what kinds of dreams these animals have. Close your 2 eyes  Now open both now see if you can wink try to close just I eye. do  your best to give a wink. if 3 seals and 3 dolphins aren napping  each with 1 eye open how many haw many eyes are closed 6 eyes close. If there are 10 dolphins and 1/2 of them are sleeping  with 1 eye open and the rest are wide awake how many open eyes do they many open eye do have altogether 15 eye 10 open eyes on the 5 awake dolphins and 5 open eye on the sleeping ones. Sloths the laziest animals out there  sleep as much as 20 hours in one day. If you sleep just 10 hours a night  how much  more then you does a sloth sleep in a week 70 more hours  since it  sleep  10 hour more than  you each day.  If albatross files for 2 hours and sleep 1/5 of the how  many minutes of sleep dose it get (reminder an hour has 60 minutes) 24 minutes  (1/5 of 120). sup pose a bunch of dolphins are trying to nap and  those who are succeeding each have1 eye open. If there are the same number of awake dolphin as sleeping dolphins and there are 40 more  more open eyes than closed open eyes  twhan closed ones how many  dolphins are there in total and how  many are asleep vs awake.  There are 40 dolphins 20 of whom are  awake and 20 of whom are sleeping every awake dolphin has 2 open  eye and for each of those dolphins  there's another dolphins with 1 open  eye asleep awake pair  has 3  open eye and 1 clouds which means there are 3 time as many open eyes as closed for the whole group since the open number  is 3 times the closed  number  the gap between them is the same as 2 sets of cloud  eyes (2/3 of the total opens) 40  is  2/3 of 60 so there are 60 open eye and 20 cooled  That must mean 20 1 eye sleeping dolphins. from called bedtime math.
