I realized im aging these days.I feel tired easily.Stamina is not as strong as i used to be few years back.

Not to say im very old,but i just felt the difference .Last time,i can go out the whole day without feeling tired.But lately,if i go out for just half a day,by the time i get back home i will be exhausted.All i want do to on a weekend is just stay at home and rest! No more window shopping and walking endlessly in town.

Probably I need to hit the gym or go back to swimming again,if not i'll forever feeling tired and no energy.
