A SPOONFUL OF SUGAR HELPS THE MEDICINE GO DOWN Magnet

I often wonder whilst walking my dog Marmite... When he sniffs and smells and seems to hunt for blades of grass to chew... Why does he choose the blade of grass..? Might there be some kind of chemicals within the grass that he can smell, something that may aid his digestion, because he is very selective of the grass..? Whilst in Bangor University - I researched 'the social behaviour of ants' and wrote an essay about it... very interesting creatures... So how about the bees? I am sure they are socially fascinating too... but I often wonder whether the animals around us - 'know more than what we think they do'... Its one of the reasons for my interest in photographing and studying them. Hemlock and cow parsley are very similar...
