For Ola, there’s no such thing as “impossible”. If you ever see a woman defusing a bomb in a silk blouse and a soft smile — that’s Ola alright. Most probably, her patience and diplomancy was trained under Tibetan monks’ watchful eyes. You can most often find her in the bio bazaar, where she buys parsley grown to the notes of classical music.
