I have had a brain haemorrhage and therefore have really struggled to feel intelligent, because I forget words, and many other nuisances. When I use this it seems as if my brain has more luck retaining any information I have learnt...its really helped me with my confidence, I have even begun to write poetry again, which was something I delighted in pre haemorrhage but had struggled with since. Can't recommend this enough if you need to remember stuff,or understand it better.
