Never go out without a knife oder a gun, to get rid of those nasty dogs! And if you see an old man in a cage, don't ask about the meaning of life, but duck and hide, because he will give you the flue instead of enlightment!
No matter how hard you train... In the end, trying to burn fat on a threadmill causes death. So it may be a better idea to stay in bed and wait for the meteor. ;-)
