One, time.
I can't do without a watch. I'm so used to having it on my wrist to look at. Sometimes I am driving the car, and I start to wonder how many minutes have passed since i began my journey... I actually can't tell you exactly. I'll probably say things like 5 or 10 mins, but never 3 mins, 8 mins or even 12 mins. That's too exact for an estimation. It gets even harder for me when it stretches beyond 30 mins. I suppose some people have an inner timer in their heads/bodies, and they are able to tell that "we've walked for around 45 mins now so given our average walking speed of 2 km/h we should have covered 1.5 km." It turned out he wasn't too far off. How did he do that?
Two, price of things.
I need to google it to know. I was recently sent this article about a family building a catamaran. I didn't have an inkling as to how much it would take to build a big 77-footer cat. Initially I was guessing around a million? Wrong. More like 5 times that. How about that semi-d in Bukit Timah? I thought 4 or 5 bucks, ha! More like 7 bucks lor. Totally off, and by a huge margin. Sigh, shake head. I can tell you how much a handbag costs though, if it helps. heh... I guess I need to expand my horizons.
