David Bowie died of cancer on 10th of January in the age of 69. Like the rest of the world I feel sorry for him. He was a brilliant musician, truly one of the greatest songwriters for all time. He was odd, creative, impressive and passionate for music. Many say that without this man there was no pop-music and it's hard not to agree. 
He changed his image for many time. In 70's he was a Ziggy Sturdust: an alien from space. Also he was a Thin White Duke wearing a formal suit. In 80's he tried himself as an actor and he became the Goblin King with funny hair and weird make-up. And as I remember he had heterochromia (when your eyes have a different eye color). 
Rest in peace, David. Thank you for your music and inspiration. You will be remembered. Goodbye, Ziggy Sturdust.

Riding a bicycle is very useful. But people don't always take a bicycle for the following reasons. One of the reasons is the absence of bicycle lanes. Let's look an adcantages and disadvantages of riding a bicycle and building bike lanes. The most important advantage is more simplier and safer riding for bikers around the city. The disadvantage is that there isn't enough place for bike lanes in the city. So, it will be necessary to allocate part of road or pavement. As a result, there will be no place for pedestrians and road capacity will be reduced. Besides, many pedestrians ignore road signs and go along the bike lanes. This impedes bike traffic and increases the probability of accidents. In addition, a lot of money is required for building of bike lanes since it is necessary to put asphalt, draw markings and place road signs. I believe that in future the bike lanes will be an integral part of roads and a bicycle will become an important part of our life.
