RAM issues

I think lately I'm out of ram. I tend to forget things easily and please tell me this not a sign of aging lor. For example, last week, I made an appointment with my SPA assistant and this week, I totally forgotten about my session lor. Two days ago, I fold my clean laundries and instead of keeping my clothes in the closet, I open the fridge... *puzzled*. I woke up in the morning today, trying to make myself a cup of coffee, after brewing.. I realised the coffee is salty lor. Yes, you're right, I put salt instead of sugar. Sei mou!
