The next time you are eating Japanese food, taste a bit of Wasabi (Green In colour) and immediately you will feel your head is on fire (depending on how much you bit off). Its at this time you must think of your Top-Eye for a few seconds. This will rejuvenate your top eye. Or else buy some wasabi from a Hyper-market (near the Japanese food counters) and you can periodically do the rejuvenation. Be warned however if you ingest more of the wasabi tears will be bountifully.This technique is not for the faint-hearted.
