Some big boys

So I have figured out that Alexander and Marcus are both going to be very tall . Alexander is 10 and he is now 4 feet 11` inches. He has grown a inch this summer . This calculation is telling me that he will be 6.4 at 21 . I am really hoping he has a great job and can get his own shoes .
Marcus is 7 and he is 4 feet 6 inches tall . He is going to be between 6.5 and 6.6 acording to this prediction - sigh .... I am kinda hoping they both stop at about 6.3- 210 lb :o)

Nathan says he is tottaly ok with being 5.9 when he is 21 and that if he ever get's in trouble he will have two giant brothers to take everyone on + he will have his black belt in Karate to take on the world with . On this note he has also grown this summer.
Nathan is 4 feet 8.5 inches at the moment .

Katie is 4 feet 3 inches at the moment and our fun prediction says she will be 5.6 when she is 21 . She says she is ok with that because she wants to be be a famous gymnast and can't be to tall .
