I’m not sure what the reason I feel tired all the time… lately, I get very sleepy in the afternoon… fatigue… well, it happen before, but not as much as nowadays… I do have lots of thing to work and think… but at the same time I do sleep late… both can be the reason… but probably, I’m getting older or  like the science said, low on testosterone… if you don’t believe me, you can read it from depo testosterone 😛 It said testosterone levels decrease after the age of 27… 😛 😛
