* Giraffes continue growing throughout their lives: Unlike humans, giraffes don't have a set age when they stop growing taller.
* Individual variation: Like any species, giraffes have different growth rates and reach different heights.
* "Middle-aged" is subjective: Defining "middle-aged" for a giraffe is tricky. Their lifespan is around 25-30 years.
However, we can give you some general information:
* Average adult height: Giraffes typically reach heights of 14-19 feet (4.3-5.8 meters).
* Males are taller than females: Male giraffes tend to be about 1-2 feet taller than females.
So, a middle-aged giraffe (say, around 15-20 years old) would likely be close to its full adult height, somewhere between 14-19 feet tall.
