(A) Do you knowthatjoggingregularly is good for yourmemory? Scientists at CambridgeUniversityhaveshownthatrunningmakes the braingrowfreshgreymatter and it has a big effect on mentalability.
According to theirresearch, a few days of running led to the growth of hundreds of thousands of braincellsthatimproved
the ability to recallmemorieswithoutconfusingthem, a skillthat is veryimportant for learning and othercognitivetasks,

The new braincellsappeared in an areathat is linked to the formation and recall of memory. The workreveals why
jogging and otheraerobicexercise can improvememory and learning, and potentiallyslowdown the failure of mentalability in
Scientists are unsure why exercisecauses the growth of greymatter, but it may be linked to increasedbloodflow or
higherlevels of hormonesthat are releasedwhileexercising. In an experiment, theystudied two groups of mice, one of which
had unlimitedaccess to a runningwheelthroughout. The othermice, remainedsedentary, formedanothergroup.
Aftertrainingsessions, the mice in the exercisinggroupscoredalmosttwice as highly as the othermice in a repeatedmemorytest for a sugarreward. On the otherhand, the sedentarymicegraduallyworsened at the test. To sum up, exercisingregularly not only can help us losesomeextra fat, but it can alsohelp us build up bettermemory.

alongverywellwithhorses. The ability to live and workcomfortablywithhorses is what led the Dalmatian to become a firehousemascot in the UnitedStates. Dalmatianshelped to keep the roadclear for the quicklymovingfiretrucks. Theycould be
seenriding on the trucks or racingalongside the horses as theyhurried to the scene of a blazingfire.
Whencarswereinvented, horse-drawncarriagesbecamelesscommon. Dalmatianswere no longerneeded to helpclear the
path for the quicklymovinghorses. Eventhough we no longer use Dalmatiandogs on fireengines, we should not forget the
important job thatthesehard-workingdogs had in the yearsbefore the invention of the car. Dalmatiandogs are truly one of
