When you get bored with the remotely practical purchases, there are plenty of other weird and wacky gizmos to distract you. The Mind Activator from Novag, for instance. This rather mysterious mini-computer comes equipped with "20 scientifically developed training programs" that allow you to increase your intellectual capacity and energy levels and scale new heights of creativity, concentration and vitality. And of course you can kiss those pesky backaches, migraines and other mortal concerns goodbye. With no negative side effects. Honest - Dr E.G. Bittener researched it and everything. (Who?) Just strap the headphones on each night and you're away - Power Rangers watch out - that is, of course, if you can cough up the HK$3500 to buy them.
If you want to activate your mind and body in less expensive ways, have a look at StimuVit, the scalp massage stimulator (a.k.a. bald-no-more?), or Evertop's magnetic self acupuncture eye massager which will "provide you a very wonderful effects for your eyes" (sic). These and other similar gems can be found at the many Boots'-like chemists in the Tsim Sha Tsui area.
