The leading marketing expert, Kerwin Rae, suffered a stroke. In a YouTube clip he personally describes how he suffered serious problems with mental clarity, mental acuity, short term memory and recall. He took Arkworld's Ark 1 'Pink Drink', which he describes as a "profound drink" with fantastic results both for his specific difficulties and his "general wellbeing". He advises, "Check it out and try it out for yourself and see what it does for you - you wont be sorry." www.youtube.com/watch?v=pldtrQID14w
