This time, with a purposeful inspection, Du Heng noticed many things.
The old man looked quite good; not every person in their sixties or seventies would necessarily possess Sun Jiaxiang's current vitality.
But to say the old man was now full of energy and in robust physical health would be pure nonsense. After all, he was a man in his nineties.
It was just Du Heng's judgment that the old man's current state wasn't yet at a stage where he needed to worry about death. With his current condition, if no sudden illness befell him, there would be no problem with him living comfortably for another three to five years.
Of course, if the old man had any hidden health issues that hadn't been revealed, that would be another matter altogether.
For a moment, Du Heng genuinely couldn't get a read on Sun Jiaxiang, so he could only explain using a literal analogy, "There's a problem in elementary school math that aligns well with the human body's development cycle."
