Age is irrelevant to me. Sharp minds usually stay sharp. It's the ears that stop listening or don't listen at all that bothers me and, I'm sure, that all the grieving parents in Arizona want is to get the same unpaid time off as someone who has a child, or cares for a sick family member, or service member. It's not about business, it's about compassion.
