Why did Matt Hamill come out of retirement?

Everything you ever wanted to know on why Matt Hamill came out of his year long retirement as a MMA fighter at the UFC can be found here. Words of encouragement can still reverberate in a person's mind from a loved one that has since long passed away. It only takes a few reminders to bring back that voice of encouragement. And it can become a powerful source of inspiration.

What beautiful music! But I can't hear it.

Indeed, words can be powerful such as in this short video clip of a blind man quietly begs for money as he sits on a city sidewalk with a sign that says "I'm blind. Please help." Very few coins were tossed his way until a lady comes up and changes the wordings on the backside of his cardboard sign with a positive message, "It's a beautiful day and I can't see it." The resulting effect was an increase on the amount of money given to him by strangers passing by. The power of words has changed for the better for this blind man who sat quietly and without complaints.

Imagine this next scenario.

You have a troupe of musicians nearby in a park playing some beautiful music that wafts through the warm summer air while a deaf beggar sitting on the ground with a sign that says,

"I'm deaf. Please help me."  

 Pretty typical signage, wouldn't you say?

But suppose a music conductor walks by and sees the situation and the pitiful amount of money so far collected in the deaf man's collection can. He gesture's to the deaf man telling him that he has a better idea for his sign hoping it'll net more coins for the deaf beggar.

And sure enough, coins and bills began dropping into the deaf beggar's can like summer raindrops.

How different would this situation be from that of the blind man?
