Sudden Turnaround

I dont know what happened to me.I used to be a forgetful boy.But its a different kind of forgetfulness.I dont forget my friends' birthdays.I dont forget my friends' names.What i forget is always the minor things like homework,what happened in a day.It seems my memory is always been erased after each day.Just like the Samantha Who? lead actress.But 2 weeks ago it seems my memory has stopped erasing after each day.I could remember things well , very well.Like, well i play Power Soccer which is a multiplayer soccer game where u play against other soccer teams from all over the world.All the teams start at level 1 and have to keep playing matches to earn experience points and ranking points (how high your rank is in your own country,i currently stand 84th in singapore).Whenever i level up i remember how much to add to my players' skills like sprinting , shooting , defending.Also i could remember my homework deadlines no matter how far is the day from the deadline.Just what really happened inside me?i dont know.I'm sure there's an answer behind this question.OK its 3.14am its time to sleep now.bye!
