<B><I>48 Hours</B></I> Explores Ways To Achieve Physical Improvement

Tonight at 10 p.m. ET/PT, 48 Hours takes a look inside the Lori Hacking case -- unraveling the web of lies told by her husband Mark, who's been arrested for her murder.

48 Hours also reports on how more and more people are going to extremes to physically improve their appearance and achieve an edge in life in "Going to Extremes," Friday, Aug. 6, at 10 p.m. ET/PT.

More than one million young people are taking steroids illegally, and for some, it has led to disastrous results, including violent mood swings and suicide.

Some teens have been getting a message that bigger, faster and stronger is better. Correspondent Troy Roberts speaks to Chris Wash of West Plano, Texas, who started taking illegal anabolic steroids because of vanity, while others, including Taylor Hooton, also of West Plano, and Rob Garibaldi of Petaluma, Calif., took them because sports coaches told them they needed to be "bigger."

All of these young men experienced extreme mood swings that included depression, and in the case of Hooton and Garibaldi, suicide.

Also, in an extreme effort to achieve physical improvement, some people are having plastic surgery as part of a vacation package-deal on an African safari. But is it safe?

Colleen Hiltbrunner of Colorado Springs, Colo., researched a plastic surgery package deal that cost thousands of dollars less than in the United States. Hiltbrunner and her husband flew to Johannesburg, South Africa, where they met "Surgeon and Safari" founder Lorraine Melvill, whose five-year-old company has evolved into a multi-million dollar business that's a boon to the struggling South African economy.

Upon arrival, the Hiltbrunners were taken to a five-star hotel and went on safari for two days before the surgery. Although the American Society for Aesthetic Plastic Surgery warns it is difficult to check the credentials of foreign doctors, Melvill insists her surgeons are a bargain, only because of the weak currency in South Africa. Correspondent Troy Roberts reports.

And, how far will a young nanny, who lost 60 pounds, go to fulfill her dream of becoming a supermodel? Contributor Maureen Maher speaks to Yoanna House, who as a child, wanted to becoming a model.

Next, House tried out for UPN television's reality show "America's Next Top Model," and was one of 12 women chosen from 8,000 applicants to participate in the series. Does House have what it takes to be the top model? UPN is also owned by Viacom, CBS's parent company.
