Ireland's Sharpest Minds


It's well known that athletes perform better when they're hydrated. And the same goes for mental tasks. Some people amaze us with their ability to recall everything. And it's nothing to do with genetics, we all can develop sharp minds. Drinking water and brain function are integrally linked. Our brains are made up of approx 85% water and our brain function depends on us staying hydrated. Who would have thought that the trick to having a sharp mind was to drink loads of water? Below is a selection of some of the sharpest minds in Ireland at the moment (who are clearly drinking vats of the stuff) from shrewd investors, advertising gurus, to sports stars with a laser like focus on their goals and victory...

Susan Denham

Denham is the Chief Justice of the Supreme Court of Ireland. She became a High Court judge in 1991. In 1992 she was the first woman appointed to the Supreme Court. From 1996 to 2010, Denham was a Pro-Chancellor of Trinity College, Dublin. She broke the mould being the first woman to hold the office of Chief Justice.


Dr. John Teeling

Dr John Teeling holds degrees in Economics and Business from UCD, an MBA from Wharton and DBA from Harvard. He has founded nine stock exchange listed companies, more than any other irish person. The razor sharp minded Teeling founded Connemara Mining, Petrel Resources, Minco, African Gold, Persian Gold, West African Diamonds and Botswana Diamonds.

Johnny Sexton

Sexton has a laser like focus in front of the posts and an ability to read the game better than anyone. This has led to career achievements including three Heineken Cup winners medals, a stint with the Lions on the 2013 tour, and a Six Nations Championship victory. It takes a special kind of player to be able to think straight under intense pressure. Sexton showed that in his decisive man of the match performance under constant attack from the French this past weekend. Aside from his rugby accolades Sexton holds a degree from UCD.


Conor McGregor

A UFC cage fighter, although well able to articulate his belief in his own fighting ability, is not the obvious choice in this list surrounded by some one of Ireland's top intellectuals, one cannot argue with his sharpness in the cage. He has risen steadily up through the ranks and most recently has knocked out fancied fighters Dustin Poirier and Dennis Siver. McGregor with several endorsement deals and his own RTE TV show has also proved adept at marketing his own brand. And he's done this in a world where there are hundreds of other similar fighters offering a similar product and vying for the same audience share.

HIs first purchases included Rexam for €660m and more recently Impress for €1.4bn. Paul is known for being publicly shy, hence why it was so difficult to find an image of him.
