Braces are a worthwhile investment, your teeth are utilized more often then your vehicle and many other things!
-say the average person eats 6 times a day (breakfast, lunch, supper and a few snacks during the day),
-7 days per week, that's 42 times a week
-365 days per year = 2190 times per year
-life expectancy is about 78 years
-take 78 minus your age at which you got braces (me, 25) =
-53 years x 2190 per year

Perhaps this will help to encourage us in those tough days of braces that they really are worth the trouble!
Do your calculation and please post your result!
