I'm a painfully slow eater, being the last person to always finish in whatever company I'm with i.e. family, friends or strangers! I'm often still eating 15-20 minutes after everyone else has finished. All too often, I don't finish everything on my plate as I fill up pretty quickly.
I do however, enjoy the whole experience of eating - savouring the taste and flavours, drinking matched wines and talking and overall just enjoying the moment.
Even when eating junk food, I'm slow. For example a small packet of chips will last me an hour as I take each crisp, suck the flavouring and making the crisp soft and then eat the crisp. A magnum ice-cream will take a good 30-45 minutes, as I peel the chocolate off first and allow it to sit in my mouth as it melts into oblivion and then I lick the creamy ice-cream until I reach the stick.
On the opposite side of the scale my brother doesn't just gulp, he gallops through his food, much to the chagrin of the person who follows him to the toilet. I'm not sure how two family members can be so completely from the opposite side of the scales when it comes to food and eating.
