1. Physical exercise prevents stroke. In men, exercise lowers the risk of cerebral hemorrhage by 40%, and that of cerebral infarction by 27%. Rapid walking or cycling suffices to achieve this effect. In women, a statistically significant effect has not been demonstrated.
2. Regular walking lowers the risk of colorectal carcinoma by 40%. Patients with colorectal carcinoma can also improve their prognosis by exercising.
