Ask HN: What numbers do you pay attention to daily?

I look up the USD/yen exchange rate almost every day. Right now it's 119.96.

How about everyone? What do you track? Doesn't have to be work related!

€/CHF exchange rate : it has gone crazy lately and working for CHF while living with € it's pretty important for me.

My one rep maxes in squat, deadlift, bench and press. To be honest, it's only 4 days/week as that's how often I hit the gym but they are the closest things to your question.

Weight, outside air temperature, bank account balance, train delay.
