Whilst genetics is clearly a key factor if we look at trends in height in the last century alone there have been some staggering increase in heights and this cannot be due to genetics as genetic effects are made in tiny steps and take a much much larger timescale to be evident. For example in the past 100 years Korean women have increased in height by 20cm, Iranian men by 16.5cm.
However, these are general trends and they don't necessarily explain why a particular individual is shorter or taller. So there is no point getting depressed about our heights - after all the reason we are on this forum is to do something about it. So stay positive. The reason I have posted this information is for education.

Nutrition and childhood disease are key factors in determining height
so the moral is get LL and feed your children properly so that no one suspects that you had LL done lol 
otherwise they would ask if the dad is average why is the child short?

Yes that's the spirit. And pay particular attention to your children's growth spurts and ensure that diet, exercise and sleep is optimal during those periods. Take a look at:

Note the significance of nutrition in the first two years.

The people in those countries 100 years ago, like my Beijing LL friend who grew up in a Cambodian refugee camp, underwent severe deprivation the likes of which would have been noticed and acted upon by authorities in prosperous countries in modern times like most people here grew up in.
Nobody is seriously going to think like "Hmm his son is shorter than him, I bet he did an unnatural height increase by limb lengthening surgery!" LOL!
nobody even would assume that.

Height has increased this much over the last century mainly two reasons. The first is epigenetics. Simply speaking, your lifestyle including nutrition and health will have an effect on your children even if their upbringing will be completely different. So several generations being able to grow up in good conditions, as was the case post 1945, will increase the average height (up to the genetic plateau, which is probably reached in some European countries). For an individual person, the effect of your lifestyle on your growth might be minimal. I think brothers with a lot of height difference are a great indication that this might be true.
The second is nutrition and diseases during your early childhood. If you are going hungry or have a lot of infectious diseases during your childhood, if can affect your height much more than during puberty. Seeing as most kids grow up healthy and won't go to bed hungry in the Western hemisphere, I doubt much growth can be stunted for a typical Westerner (unless you become anorexic as teenager).

Are you a biologist/related field?

Nope, just wrote what I gathered from reading studies/articles about studies over the years.

Sleep and depression?
Quote from: Bruce Wayne on August 26, 2020, 10:32:06 PMSleep and depression?
You yourself have searched for studies linking sleep to height and have found little evidence that it can truly stunt growth. Depression is an interesting topic, there are things like psychosocial short stature that can happen with extreme stress, abuse or trauma.
