If you have watched Pink, then chances are that you have some questions in your mind. Let me guess, one of those might be 'why was Amitabh Bachchan wearing that creepy black mask?'

The mask that Amitabh Bachchan was seen wearing in the movie, Pink, is actually an elevation training mask.

The mask restricts breathing which makes people feel like they are at a high altitude. It basically gets people out of breath sooner than normal. However, the composition of air remains the same as it is when you breathe without the mask. It helps condition the lungs and strengthen the diaphragm, thereby increasing the overall lung capacity and improving oxygen intake. It also claims to increase mental focus and decrease workout time. For the same reason, it is used by athletes during fitness training. Here's a video of cricketer Virat Kohli working out while wearing the same mask:

Needless to say, the mask added a lot of character to Mr. Bachchan's role in the movie.
