Just an example for a multi-line while condition;
the last exit status before the do counts.
Code:
while
    echo "What is your name?"
    read name
    echo "What is your age?"
    read age
    echo "What is your sex?"
    read sex
    echo "so you're a $age old $sex called $name, is that right?"
    read right
    test "$right" != Yes
do
    if test "$right" = No
    then
        echo "Please enter your information again."
    fi
done
echo "Great, thanks!"
