Lets work through this methodically...

 

How many times do you breathe in a minute? How would you calculate the number of times you breathe in a day?

I estimate that I would breathe about 15 times a minute.

Times 60 to work it out per hour.

Times 24 to work it out per day.

This gives 15 x 60 x 24, which is 22,500 times a day.

 

How many times do you blink in a minute? How would you calculate the number of times you will blink in a week?

I estimate that I would blink about 5 times a minute.

Times 60 to work it out per hour.

Times 24 to work it out per day.

Times 7 to work it out per week.

This gives 5 x 60 x 24 x 7, which is 50,400 times a week. Which is a lot of blinking...
