it's more than a charming hallmark of youth.
People don't wake up at 50 or 60 or 70 and suddenly decide it's important to participate in life. They're the same few who show up to deliver Meals on Wheels week after week, year after year - who *volunteer* - not because they have time on their hands -but because they have always understood the theory of that life is made better one small act at a time. That takes a non-passive idealism.
I keep the little sticker that says "I voted" on my computer - to remind me that it takes a lot more than posting here to effect changes.
