It ’ s the greatest feeling to be able to help . ‘ I ’ ve been through the racing world , so hopefully I ’ ve found a good solution that could help him shape his own solution . I ’ m really proud of that. ’ Asked if his brother was strong , Hamilton said : ‘ He ’ s got very big fists . If he caught you with a punch , you ’ d know about it . I always make sure that I show him “ I ’ m your older brother ” . ’ Hamilton crosses the line in Bahrain ahead of Kimi Raikkonen to claim his third win from four races this term .
