How fast you can run a mile is almost totally irrelevant to anything else in life except when you are so slow that it would indicate morbid obesity. The only kind of exercise that is really important for overall health/fitness is hard resistance training. That covers cardiovascular fitness, metabolism, muscular strength, bone strength, etc. Running is only useful if you plan to compete in running events - it is not itself a very productive form of exercise.
This is hilariously misguided. There are so many guys who can bench and squat a good amount, and are in terrible overall physical conditioning. They have beer guts, would tire out very quickly in almost any measure/test of physical conditioning (other than pure strength at their pet lifts). But they can pump a few good reps of a huge amount weight. They are strong, that's it.
A runner will live much longer and be much healthier than the lifter I described.
Having said that, a combined approach is certainly the best for overall conditioning and health (pure strength and endurance work). And yes, a slow distance runner many times won't be a very good athlete at other things. He likely will still be very healthy though.
