Normally there are two types of sprinters. The first type is short sprinters who are no taller than 1.8 meters. Their leg muscles are stronger and their running pace is faster.
The other type is tall sprinters whose limbs are also longer. Their pace is slower, but every step they take will cover significantly more distance than short sprinters.
Chen Zhao clearly did not belong to either of these two types. He was quite tall, over 1.8 meters to be precise, but his limbs were shorter than normal athletes. Even if his body was as strong as an athlete, he would still be unable to take part in track and field, especially sprinting.
Of course, he had never thought of becoming an athlete anyway.
Chen Zhao liked his current life; it was fruitful but also filled with free time.
On the other hand, athletes had to be serious and train themselves until exhaustion every single day.
Furthermore, Chen Zhao's age was no longer suitable for an athlete.
