How to prepare for alien invasion

Busy day, and then gone for a week, so I leave you with the most useful advice I've seen today:

SAN FRANCISCO (Reuters) - When the aliens finally invade Earth, you may wish

After all, they have written "An Introduction to Planetary Defense", a primer
on how humanity can defend itself if little green men wielding death rays show
up at our cosmic doorstephttp://www.reuters.com/article/domesticNews/idUSN0934498720070425

Enjoy.
