i watched something a while ago about peoples time clock's something to do about the time of day you were born, i know years ago i worked 3 months on night shifts 5pm to 7am and it was the best i ever felt, slept mint through the day and was wide awake all night while the other lads were dead on there feet, its a bastard if i go on a stag do now though as i am always the last man standing at 4-5am ready to go on and all me mates are in bed ,
