Tuesday's Assignment

Hi, my name is Da-Som Baek.
My opinion about Tuesday's Assignment is that left-handed or right-handed isn't related smart.
Because though left-handed changes right-handed, this person doesn't  change logical person.
And today's text say "Some right-handers have a strong right brain, and some left-handers have a strong left brain".
There are many exception.
So, I don't think that right-handed/left-handed isn't connected people's ability.
