Athletes' physical fitness is much stronger than that of ordinary people, but they also have their own diseases, especially heart problems, which have a great influence on athletes. This time, Eriksson had a cardiac arrest on the court, and some African players died suddenly on the court in the early years.
Among NBA players, last season's Nets player Aldridge also suffered from arrhythmia, which led to the direct announcement of retirement. C Ronaldo also had heart surgery in his early years, but fortunately, the technology at that time was very advanced, and the problem of C Ronaldo was not particularly serious, so C Ronaldo recovered after the operation at that time, which had no effect on C Ronaldo later.
In fact, Messi had physical problems in his early days. He is different from Cristiano Ronaldo. Messi was dwarfed at that time, which had a great influence on an athlete. But with the help of Barcelona, Messi also went to Spain for treatment, which made Messi's later glory. For athletes, their physical fitness is better than ours, but they will also encounter various diseases, especially heart disease, which is very dangerous for an athlete.
