Spine injury but not exactly because he's obese (I think I saw his PL but i can't remember if it has irl face or body photos). What I remember is that it just... prevents him to sit for long duration of time, which means that long-distance flight will be hell for him unless he has enough money to afford those VIP seats thingie I can't remember the name.Is it known what exactly he has that prevents him from doing 3D?
I have read that he got a spine injury because hes morbidly obese but I dont quite trust this claim
I haven't followed him enough to know the full extend of how his spine's issue is, but considering that long flight thing, best guess is less on "is he can move around" and more on "can he survive sitting while flying to Japan before he can debut his 3D?"
