Is the universe changing?

How do older mens bodies allow them to produce sperm late in life?
Men are a sperm producing factory. Because they are making sperm their bodies are already old and getting older and since it takes so much effort to convert normal cells into sperm cells, they are lacking energy and health. Sperm is to be conserved especially in old age if the elderly wants a longer and healthy life.

How do people and children get bigger and not smaller?
As you grow, there is a cell in your body when you're a baby. As the cell multiplies into more cells, you grow. The more cells there are, the more complex that organism is. Cells are continually multiplying and dying off, to be replaced by new cells. How much we grow is decided by our hormones and our genetic makeup, that is, what our parents were like. For example, tall parents are more likely to have children who also grow into tall adults. People do actually shrink when they get older. The discs between the vertebra in a person's spine compress together over time, and this makes people actually shrink slightly with age. Osteoporosis also causes people to shrink with age, as it causes bones to break down, and new bone growth doesn't take place as the bones are missing vital components to help them regenerate.
Do older people have more cells than babies?
No, older people generally have fewer cells than babies. As we age, the number of cells in our bodies may decrease due to factors such as cell death and reduced cell division. Babies, on the other hand, are growing rapidly, so they tend to have a higher number of cells compared to older individuals.
How does age changes affect the heart?
Our bodies wear out, like all things, as we age.
