I have identical twin boys, nearing 3 1/2 years old.
It's like a double control group, both with the same genes and the same upbringing, right down to nap times, food eaten (or at least offered) etc.
One has always been half a pound or so heavier, and very healthy other than some normal colds / croup from the bio-warfare that is daycare. His twin has eczema, asthma and hayfever. Growing out of it slowly, thank goodness.
There are both typical Aussie boys. Wrestle like bear cubs, couldn't keep them inside if you wanted to, covered in dirt and grass within 5 minutes of putting their shoes on (if you can convince them to) in the morning.
So there you go. It may all have an influence, but there's no single cause.
