The two biggest changes in the population pyramids of Germany in the periods of 1965 and 2015 are that in 1965 the population pyramid is well structured by age, while in 2015 the pyramid is increasing in size in its upper parts but becoming thinner in the lower parts.
In 1965 we have the ''baby boom'' period, where the birthrates went up, so there was a big percentage of young population. The population pyramid was wider at the bottom because of the high birthrates, slowly decreasing in the middle sections, and becoming smaller and smaller towards the upper parts.
In 2015 though, the population pyramid looks much different, with the middle section being the biggest, the lower part much thinner, and the upper part is also bigger. This is due to few reasons, like the shift from rural to urban population, pursuing of careers of the youngsters, being too expensive in the cities to rise more kids, and all of that contributed to a significant drop in the birthrates in the country. But also, it is worth mentioning, that the lifespan has increasing, so the population is aging and it is becoming older and older.
The tilt of the earth is what influences the seasons. Not the distance. The distance stays the same all the time because of gravity.

Ok so the answer is magnetism
Developed countries have better medical facilities because they have more money and are able to afford equipment which is often very expensive. Due to having more money, their medical facilities can be equipped more expensively. While this doesn't always mean it is a better facility, it often is the case.
So in a nutshell, because developed countries have more money, they are also able to provide better healthcare and better medical care in their medical facilities.
