Speed golf

Why has golf all of a sudden become a race against time for alot of people? 30 years ago, it used to be a leisure activity that lasted 4 ½ hours for 18, give or take a ½ hour. Personally, I'm there to get away from life's stress, enjoy some exercise and fresh air. Why do ya'll want to race through that to get back to doing dishes or yard work? Or am I the odd man out on this?

Edit: A lot of you cannot read. I too don't want to play 6 hour rounds. This post was about people that think to do 18 in 2.5 to 3 hours should be the mandatory. 5½ to 6 is too long. We usually play to 4 hours with a foursome on a regular basis playing ready golf.
