Exercise is a lot more gratifying if you count what it feels like.

Number of flight of stairs to reach nth storey
= (n-1) x 2
First Example: To get to the 2nd storey of any building via manual labour from the 1st storey, one would have to climb two flight of stairs.
Second Example: To get to the 3rd storey of any building from the 1st storey, one would have to climb four flight of stairs.

So today started out like any other day. Dressed in a dark grey long-sleeve shirt with my customary black pants, i walked to the office from the train station. And because its an old building, there is no lift. So i climbed the stairs to the office at the 5th storey.

Total number of flight of stairs climbed so far
= (5-1) x 2
= 8

Before i could even sit on my chair, my boss intercom-ed me and i was asked to participate in a discussion. So i climbed down to the 4th storey where the conference room is.

Total number of flight of stairs climbed so far
= 8 + {[(5-1) x 2 ] - [(4 - 1) x 2]}
= 8 + (8 - 6)
= 10

During the discussion, my boss invited me and my colleagues to join him in an inspection of a newly constructed building. Since its a chance to learn more, i went along with the rest of my colleagues. We drove there.

Total number of flight of stairs climbed so far
= 10 + [(4 - 1) x 2]
= 10 + 6
= 16

When we reached there, we were told that the lift wasn't ready yet. Since our boss suggested that we start our inspection from the top floor down, we climbed to the flat roof which is designated as the 8th storey.

Total number of flight of stairs climbed so far
= 16 + [(8 - 1) x 2]
= 16 + 14
= 30

Having inspected the top floor to our satisfaction, we slowly made our way down while inspecting every floor.

Total number of flight of stairs climbed so far
= 30 + [(8 - 1) x 2]
= 30 + 14
= 44

After my boss gave his debrief and drove us back, we went back to the office to put our stuff down.

Total number of flight of stairs climbed so far
= 44 + [(5 - 1) x 2]
= 44 + 8
= 52

After that, we went for lunch.

Total number of flight of stairs climbed so far
= 52 + [(5 - 1) x 2]
= 52 + 8
= 60

After lunch, we headed back to the office.

Total number of flight of stairs climbed so far
= 60 + [(5 - 1) x 2]
= 60 + 8
= 68

While doing my work, i discussed an important matter with someone over the phone. Since i'm really busy these days and forgetful due to work, i thought it best to settle the matter now. This meant that i had to travel to his office.

Total number of flight of stairs climbed so far
= 68 + [(5 - 1) x 2]
= 68 + 8
= 74

Joy of joys! His office has a lift!

After settling the matter, i headed back to office.

Total number of flight of stairs climbed so far
= 74 + [(5 - 1) x 2]
= 74 + 8
= 82

I went home at 7pm.

Total number of flight of stairs climbed for today
= 82 + [(5 - 1) x 2]
= 82 + 8
= 90

My dark grey shirt has been wet from my perspiration so many times and dried so many times, that i think its no longer black.

Its probably white now, due to the 1000 tons of salt deposits from my umpteen-dried-up-perspiration.
