```Ding Fan looked through the crowd at the elderly woman lying on the ground.
She was a woman around sixty years of age, her hair already mixed with black and white, her pale face looking extremely haggard.
At that moment, the old woman was convulsing all over, her breathing very rapid, her eyes rolling back in her head vigorously. Without using Divine Sense, Ding Fan could already see what was happening to the old woman.
It was clear that the old woman was suffering from a heart attack.
The heart is the most crucial part of the human body, and heart disease is a very common illness among the elderly.
To this day, modern science has still not found a cure for heart disease; this kind of illness can only be managed with rest.
When a heart attack occurs, the patient must be taken to the hospital immediately. If the treatment is delayed, it is very likely that the patient could die due to improper intervention.
