Very few rugby players representing their countries will be 35 years or older. There are very real and physiological reasons for this: their bodies and reactions are not what it used to be. They may have the ball sense, the experience and wisdom, the ability to analyse the game, to plan and think, but they have lost speed.
They are not as fast and nimble on their feet as they used to be, and their reaction time may be slower.
Many rugby players had suffered more than one torn knee ligament and a serious shoulder injury by 28 - 30. Other common injuries include ankle injuries, broken ribs, neck and back injuries and concussion. An older player will need more time to heal from an injury than a younger player. This is where temptation creeps in to use anabolic steroids, the banned substance that can fast-track healing and training after an injury.
