Because back in the good ole' days, most people were happy. Before we got this Internet(which I am SO happy we have) and television and cell phones and whatever. Everyone used to communicate with each other face to face. Not through Facebook or Twitter. Everyone was playing sports outside, soaking up some Vitamin D and chatting about being best friends and paying 75 cents for a movie in the cinemas(in, like, the forties. hahahahahha.)
Oh, yeah. Life was good.
Now, most people are depressed and hate their bodies and do so much drugs it's a wonder the human race still exists.
People just aren't happy anymore.
And, you know what?
That is pretty sad. The fact that we're running out of oil and happiness. In about fifty years, we'll have no oil left. What about happiness?
PS: You know what would make ME happy right now? If you'd go and MAKE ME A SANDWICH!
PPS: I'm kidding.
PPPS: Sort of.
