If some fight can take place very late, then I won’t always wait to watch it either, but will watch the replay in the morning.
Of course, when I watch the match of my favorite team especially if it is a competitive match I become more excited even though I have not bet but betting on such a match also helps double the current excitement. For example, in the recent Galatasaray - Manchester United match, after Manchester United took a 2-0 lead, I saw 15 odds for Galatasaray to win and as a Galatasaray fan I bet on this result. Afterwards, the match continued so well that when Galatasaray attacked and scored a goal, I was twice as happy and twice as excited because if Galatasaray won the match my favorite team would win the match and I would make a good profit from the live betting with 15 odds, I would.
On the other hand, when I bet on a team that isn't my favorite I get excited only based on the match score. In other words, as the probability of winning the bet I placed increases or the risk of loss occurs in the last minutes I become more excited than usual. Of course, when I just want to watch the match without placing any bets this excitement doesn't exist and I just sip my beer while watching the match in an enjoyable way.
