Brain exercise: exercising our Frontal and Parietal lobes

Ear­lier today we had a fun Exer­cis­ing our Brains class. We cov­ered much research ground, and exer­cised our Frontal Lobes (that deal with plan­ning, among other things), and Pari­etal Lobes (calculations).

Now it is your turn: please try to guess the answers to the ques­tions below (you don’t need to know, or research, the right answer, sim­ply try to “guessti­mate” an appro­pri­ate range).

1) How many times heav­ier than a mouse is an elephant?

2) How many fire­fight­ers are there in San Francisco?

3) How many trees are there in NYC’s Cen­tral Park?

The Answer appears as a Com­ment below.

    2. 650

    Again, the key here is to try, plan the steps towards the solu­tion, and do the men­tal calculations.That’s the brain exercise.

    Answers:

    1. Around 150,000. Ele­phant: 4,000 kg on aver­age; mouse is 25 grams.

    2. Around 350 fire­fight­ers on duty on any given day, out of a pool of 1700 fire­fight­ing and emer­gency med­ical field personnel

    3. “There are over 26,000 trees of approx­i­mately 175 species in the Park.” More infor­ma­tion at http://www.centralparknyc.org/17613/4604933

  4. […] 40. A few guessti­ma­tions like the ones I was asked in McK­in­sey inter­views years ago. […]

  5. Mitch says:

    I said 80000 times as heav­ier (ele­phant 2000kg, mouse 25g).

    Im aus­tralian so i have no idea about those american-based questions.

  6. Aaron says:

    1. 14,000 times heavier

    2. 1,300
