The Disappearance of the Ashtray
It's tough to portray just how ubiquitous smoking was to a modern audience. You would go to a restaurant and the first thing your hostess would ask is "smoking or non"? I remember standing in a checkout line in the 80s as a child and being fascinated with the billowing clouds of smoke an old lady blew.  I remember coming home from bars reeking of smoke, even though I didn't. Even teachers had their own lounges that reeked of smoke (nowadays in some states you could be fined for possessing Tobacco products on school grounds!).<p>I often think about how much younger today's generation looks and I can't help but think it's due to the huge reduction in the amount of people who smoke. The people I grew up with who still smoke look 5-10 years older than their peers.
