The skull of a Bengal tiger rests along side the skull of a domestic cat.

Notice the proportionally smaller braincase and eyes in the tiger, and the much larger flanges for muscle attachment, in comparison to the overall size of the skull.

As animals scale up in size, more muscle is needed to bear the additional weight and counteract the effects of gravity. To anchor the increased mass of the muscle, bones become more robust. Thicker, heavier, with larger flanges, and deeper hollows to provide the additional muscle with leverage. 

It’s a cyclic system. More muscle is needed to support heavier bone which in turn supports more muscle…etc. 

You’d think it could go on forever, but as animals become larger and more powerful, they also become heavier. For land predators, the cycle reaches a cutoff size when the increasing weight begins to negatively affect agility, maneuverability, and the ability to successfully catch prey.

HOW TO SURVIVE A HEART ATTACK WHEN ALONE Let’s say it’s 6.15pm and you’re going home (alone of course), after an unusually hard day on the job. You’re really tired, upset and frustrated. Suddenly you start experiencing severe pain in your chest that starts to drag out into your arm and up into your jaw. You are only about five miles from the hospital nearest your home. Unfortunately you don’t know if you’ll be able to make it that far. You have been trained in CPR, but the guy that taught the course did not tell you how to perform it on yourself..!! NOW HOW TO SURVIVE A HEART ATTACK WHEN ALONE… Since many people are alone when they suffer a heart attack, without help, the person whose heart is beating improperly and who begins to feel faint, has only about 10 seconds left before losing consciousness. However, these victims can help themselves by coughing repeatedly and very vigorously. A deep breath should be taken before each cough, and the cough must be deep and prolonged, as when producing sputum from deep inside the chest. A breath and a cough must be repeated about every two seconds without let-up until help arrives, or until the heart is felt to be beating normally again. Deep breaths get oxygen into the lungs and coughing movements squeeze the heart and keep the blood circulating. The squeezing pressure on the heart also helps it regain normal rhythm. In this way, heart attack victims can perhaps buy precious time to get themselves to a phone and dial 911.
