OMG, or I suppose, O-Me-God Facts say, throw a mouse or a bug from a great height, maybe even an airplane and it will survive the drop. The reason is that terminal velocity, the speed that should kill you when you hit the ground, varies with your size. If you are big, you will hit the ground hard. If you are small, you will barely feel it. It is like getting punched with a force equal to your body weight. A mouse weighs next to nothing and a bug even less, so hitting the ground is at worst like hitting a hard mattress. This has several real world appllications.
First is health. Don't be fat; the fatter you are, the harder you fall.
Second, psychology, don't be fat-headed, even if you got handily elected to high office. Sometimes the voters don't know what they are doing but come to realize it soon enough. The fatter your head, the harder it will hit the pavement when you must fall off the pedestal you erected.
And third, political in-fighting. Obviously never pick a fight with someone bigger than yourself. But also never pick a fight with someone lesser than yourself. No matter how much the little guy keeps punching you, ignore it, because if you punch back and miss, the terminal velocity of your far heavier punch will drag you along with it to your own downfall.
Plus a giant dinifies a midget by taking up his challenge and a midget rises to the stature of a giant by calling his dare. If the guy really annoys you, get someone his size but meaner to strike back for you.
