As a former football player who has carried a football more than 4 000 times trust me I did not go into ballroom dancing with my body being 100 percent with no aches or pains or ailments coming with me. When you're dancing you're doing stuff that your body's not used to and so you start to aggravate those old injuries.
It's never really that much fun for me to do movies anyway because you - you know you have to get up very early in the morning and you have to go in and you spend a lot of time waiting around.
