Meet Timmy. Timmy is 25, 175lbs and in decent shape. Due to his love for <insert sport>, he does alot of cardio. Timmy holds his hits for 10 seconds apiece. He exhales and that is the end.

Meet Jonny. Jonny is 55, 5'4", 350lbs and in terrible shape. Due to his love for cheetos, he has bitch tits and he hasn't seen his dick. He believes that holding his hits for 3 seconds is plenty. (and it is). But if he holds his breath for too long, he gets a little lightheaded and knocks over his cheeto bag.

Moral of the story, if you in such terrible shape that you can't hold your breath for more than 30 seconds, you should probably worry about that spare tire around your waist than your 'brain cells'.

LIP, can you not hold your breath for 30 seconds?
