Losing happens, I can't say I'm anyhow sad or frustrated after I got beaten, except when I was winning or at least equal in a position and a huge blunder ruined it all for me. But even then I'm aware that the other guy is happy over his victory, and the loss doesn't appear as bad anymore.
It's just a pity that I wasted precious minutes in a game which I was already destined to lose, and that's the only thing which can't be redeemed. There's always a sucker with too much points around the corner, but time is finite.
How much does it bother you to lose a game, and for how long, typically?
I believe there must be some amount of disappointment at losing - an emotional factor at some level for some quantifiable amount of time, if for no other reason than we are losing an investment, however small it is, and we are human. Unless we are like the proverbial Zen masters we have attachments. And how do you actually react? Do you ever swear, act out, sulk, or are you completely oblivious without ever being fazed even momentarily?
