In Waikiki, traffic is part of the passing scenery

Yes, there’s a lot of traffic in crowded Waikiki. Watching cars, buses, trolleys, taxis, bicyclists, scooters, Segways and pedestrians jostle for space along this densely populated stretch of paradise raises an obvious question: Does something need to be done?

Most stakeholders say yes. Some complain about the growing number of private trolleys blocking traffic. Others want more room for bicycles. Others complain about pedestrians having to dodge Segways.

No doubt a few well-placed rules and road design modifications could smooth out some of the chaos. The best solution would make it easy for folks to get in and out of Waikiki without their cars. But Waikiki will always be crowded — at least we hope, for the economy’s sake.

Beware the promise of dietary supplements

Given the disturbing health questions, it’s with some relief that the manufacturer of OxyElite Pro has issued a nationwide recall of some of its weight-loss products — under threat from the Food and Drug Administration.

It’s been more than two months since reports started emerging that at least five Hawaii residents had developed acute liver failure after taking a weight-loss supplement.

On Sunday, the FDA said the products involved in the recall include OxyElite Pro Super Thermo and OxyElite Pro Ultra-Intense Thermo capsules and OxyElite Pro Super Thermo Powder. The FDA website lists the UPC numbers.

Dietary supplements are a huge consumer market, given that folks are constantly seeking ways to improve their bodies and overall well-being. But at the first hint of questionable products, consumers should be akamai enough to heed the wisdom of "caveat emptor": Let the buyer beware.
