After talking about not having many photos, he talked about his weight while in the army and stated, "When I was in the army I gained 19kg (41 pounds), but now I've lost 14kg (30 pounds). I didn't want to look too old so I had a diet of eating high sodium and low protein foods. It's a bit silly, isn't it? So I lost weight and now I weigh around 65kg to 66kg (143 to 145 pounds). I lost a lot of weight, didn't I?"
