We need occasional reminders of what people are capable of doing in times of difficulty and crisis. The above video is one of these reminders... A group of bystanders comes together and performs a more or less superhuman act to save a life.
Remember this lesson as the future grows darker... In the immortal words of Galaxy Quest, "Never give up! Never surrender!" :) With people coming together for mutual assistance there's nothing that can not be overcome no matter how overwhelming it seems at times.
