Dr Andy Ho has written a very helpful article to highlight the dangers of brain injury in certain sports ("Beware brain injuries in sport"; last Saturday).

Although sports are positive for health and healthy competition, we need to be mindful of such dangers and take the necessary precautions.

Boxing is one such sport that can result in head injury, and subsequently brain injury.

Some boxers have died in the ring, while some of those who have retired are plagued by post-concussion brain deficit, which probably results in Parkinson's disease and other associated problems.

Other combat sports are becoming more popular, and injuries from such sports may be even more damaging.

There is no guarantee that injuries will not result from any sport, but a careful approach in training and competition is mandatory.

One such precaution is to have a doctor present during such competitions, and we should have the wisdom to stop a bout when we suspect that serious injury is likely to ensue.

Competitors also need to be mindful of such dangers, wear headgear and take all other necessary precautions.
