I don't like summer, neither winter, but especially winter, because it reminds me of the accident: Cerebral Hemorrhage.
According to the specialist, there's no special way to avoid such sickness from happening again.
"Maintain your health and drink lots of water." That was the best advice given to my doctor. In other words, don't stay up late and if you were to drink, don't drink too much.
Well, I'll try to keep this in mind whenever I go out next time.
