Neither boxer was happy, both wanted a more conclusive result, so they met again in 1975, in the famous “Thrilla in Manila.” This time Ali won in the fourteenth round, but neither man was ever the same again: these three fights had taken too much out of them, shortening their careers. Pride and anger had overtaken their powers of reason. Do not fall into such a trap; know when to stop. Do not soldier on out of frustration or pride. Too much is at stake.
