    {
        // suspend execution for 5 seconds
        yield return new WaitForSeconds(5);
        print("WaitAndPrint " + Time.time);
    }    IEnumerator Start()
    {
        print("Starting " + Time.time);        // Start function WaitAndPrint as a coroutine
        yield return StartCoroutine("WaitAndPrint");
        print("Done " + Time.time);
    }
}
