Hard drive health by crystaldiskinfo

I used the program Crystaldiskinfo on my six years old laptop disk. It gives a caution "05 reallocated sectors count current:100 worst:100 threshold:50 raw values:0000000000088". Is this normal or do i need to worry about my hard-disk? Could you please explain in very simple terms?
