Today, On the phone, I couldn't speak during first few seconds, I was finding somewhere quiet to speak. Because At that time I was in the office and it was lunch time. In During lunch time, most of  the people take a nap so, I don't want to disturb them. By the way, I've worked for hanwha techwin just for about 3 months. Before this company, I had worked for samsung techwin for 10 years. but my company was merged with hanwha group on july this year. so, So my company name was changed to hanwha techwin. And after the ages age of 40, I recognized that I need some exercise. I like soccer and basketball, but It's difficult to find people who want to play and get together and I'm afraid that i get hurt during exercise. so, So I prefer marathon, because I don't have to worry about injury and arrange the time to play with other guys. I usually jog by the riverside. I prefer reiverside to than gym while gym feels stuffy, riverside provide fresh air.
