Now that we understand biological factors that contribute to acne, we can focus on environmental and genetic aspects of disease. As far as genetics are concerned, adolescents with a family history of acne tend to also have disease.

At some level, it's way our genes program our glands and hormones, which in turn affects how much oil glands produce.

Other factors can actually make acne worse. Greasy make-up, and other types of drugs, usually androgens, can cause acne to flare up. Women are more at risk as their menstrual cycle nears each month.

Wearing tight collars, hats or even bags over shoulders can also contribute. Many times weather can also affect acne. A hot and humid day can cause a breakout.

Also, squeezing, popping or picking at lesions (pimples, whiteheads, blackheads and zits) will not help at all. In fact, oil and bacteria on your hands will actually clog other surrounding pores more.

So not everyone can avoid Acne, but if you know causes, then there's a chance to prevent it.

In late 1994 city of Los Angeles had chance to repaved Olympic Boulevard with hot-mix asphalt which included 15% asphalt rubber millings from that same street.

How often will California use this material to law a quieter foundation for its streets?

Nobody knows. By decreasing noise on highways, this asphalt technology gains ground with transportation department of California. At same time it also loses

popularity because of negative byproducts it elicits, i.e., bad smell, smoke, and sticky material base.

Tom Kuennens also stated that, "The California's Rubberized Asphalt Concrete Technology Center promotes use of crumb rubber from scrap tires in roadway rehab projects by providing education, and consultation services to local agencies within California."
