A study by the University of Eastern Finland determined that cynical people were three times as likely as optimists to get dementia. Put on your rose colored glasses!

"Cynicism masquerades as wisdom, but it is the farthest thing from it. Because cynics don't learn anything.
Because cynicism is a self-imposed blindness, a rejection of the world because we are afraid it will hurt us or disappoint us. Cynics always say no. But saying 'yes' begins things. Saying 'yes' is how things grow.
Saying 'yes' leads to knowledge." Stephen Colbert 2006 Commencement Address Knox College
