Mr. Ma Yanchu (ex-president of Beida University)
attribute his long life to two things - taking
cold shower each day and climbing mountain each
week.
Better shower should alternate between cold
and hot. When water is cold, blood vessels contract.
When water turn hot, blood vessle expand.
This rapid contractrion/expansion of blood vesssle
constituite good cardivascular exercises.
