I'm worried by the meteor hit in Russia's Ural Mountains. It landed in a lake near Chebarkul rather than on top of the town. I can imagine how frightening it must have been for the residents nearby. The shock waves knocked out windows and, besides injuring nearly 1,000 people with flying glass, must have damaged eardrums. Mothers would have hugged their children to combat the fear of the unknown. In times of stress, it is natural to think of our families and pull together to help each other.

Some help is potentially at hand - the dedicated Asteroid Terrestrial-impact Last Alert System or Atlas, designed to give at least a few days' notice of impending asteroids by scanning the whole sky every night. Also, amateur asteroid enthusiasts share vital information. But the problem remains. We could be taken unaware by a completely unknown asteroid at any time.
The best thing to do is live each day as if it will be your last. How often do we suffer from the, 'if only' thoughts when a beloved pet or relative dies? Love your family and those around you now. I've often read these, or similar, words from wise men, 'Now is the only reality'.
