  3. Questions:
    what do you mean by family? I am adopted and I consider my friends as an important part of my family.
    Assuming the following:
    Grandfather + Mother + elder brother + myself + my cat = 40 x 5 = 200
    Grandmother = 80
    Mother = 50
    Me = 12
    Brother = 28
    Cat = x based on cat yrs

    1 grandparent = 85 years

    father = 45 years

    mother =40 years

    I'm mathematically challenged
