On the face of it that looks low, but you could be a midget 3 ft tall. I certainly wouldn't want to be below 70kg (22 bmi) just looks too low.
I could easily get from 72 to 80 no problem by eating junk food and drinking too much
Kasikorn transfers seem to settle in seconds usually, a new account or large transfer may take longer. A very small minority have issues but likely due to money laundering checks or suspicious activity
What do you eat for beakfast? a block of cheese? I've found porridge is the most filling but can't have that every day, English breakfast i rarely eat but good after a drinking session
Frozen is certainly good, fruit and veg always available when you want it, with fresh you are under pressure to finish it or throw it. Here in Thailand i freeze peeled ripe bananas, very nice and good dessert or for milkshake
