Because
Typing is the most fun thing, because if you like the writing activities and you often do typing using your own keyboard, then you will feel the running time is very fast, just for a moment you sit and write something on your computer or laptop time it's been a long time, it's like that time if that time makes you negligent. But if you like activities other than typing then this typing activity will be very annoying to you guys, I dare guarantee.
So if I think, better than now you like this typing activity, because jam can add to your experience, also can accelerate you in terms of writing.
