Catching a cold certainly have an effect on my physical and mental performance. I stammer now and then, have pronouciation problems, always choke on the food I eat and get really tired after 15 minutes of slow walk. Today my diet consists of 4 panadols (for children), a panadol cold relief, 2 vitamin c tablets, a spoonful of wierd black chinese herbal substance that tasted like glue-- all during my visit to Rina the sinseh, who had to take out the dictionary and explain to me what is the difference between cold and flu, mucus and phlegm and the definition of 'catarrh'. Then she made me eat 2 bowls of porridge that could have landed me in the ICU if I'm unfortunate enough... haha, actually her cooking is kind of good.
