HEALTHY AND LONG LIFE IS A FEW EQUATIONS AWAY

     We all know 'bot-belly' is not good for us.  How much life we will lose because of big belly?  Here math-(a little) comes into play. 

     First, we have to find waist to height ratio -r.  Suppose your height is 172 cm and your waist perimeter are 96 cm. The ratio is 96/172=0.56.  You can have the ratio up to 0.5.  More than 0.5 is not good.  That is your waist circumference should not exceed half of your height-both for men and women. 
    Suppose you are 30-year-old nonsmoking male.  You can calculate the 'years of life that will be lost' using the equation given below. 


Years lost -y = 616.67r^3 - 920r^2 + 467.81r - 81. 
r-waist to height ratio. 


     It is a ugly polynomial equation.  We have similar equations for male aged 50 and 70; for female aged 30, 50 and 70.  I do not want to give all of them here and threaten you.  But all the six equations give a nice family of curves.  They are given below. 

 

CONCLUSIONS FROM THE CURVES 
1. Men lose more years of life than woman for the same ratio r. 
2. More years of life lost when ratio increases from an already higher number. 
3. The effect of ratio on 'years lost' diminishes with age. 
4. Ratio of 0.5 minimizes years of life lost. 
    How to increase your life span.  You have to reduce waist size.  But do not go for liposuction.  You have to reduce the belly fat through better nutrition and exercise.  Hence go for, low carb high protein, high fiber, good fat and low energy density foods.


  How to use the equations, if your age is other than 30, 50, and 70 
For male ?


Age 30: Years lost =616.67r^3 - 920r^2 + 467.83r-81  -----1 
Age 50: Y = 183.33r^3 - 180r^2 +45.167r-0.5 ------2. 
Age 70: Y = -83.33r^3 +245r^2 -188.67r+43.5------3. 
For female: 
Age 30: Y =150r^3 -175r^2 +69r-9.4  ---4 
Age 50: Y= 116.67r^3 -130r^2 +48.33r-6.4 ---5 
Age 70: Y = 60r^2 -58.4r+14.21 ----6 


   If you are non-smoking male aged 40, take equation 1 and 2; multiply the result of each equation by the factor 0.5 (since the age 40 is half-way between age 30 and 50 ); add the two answers; you will get loss of years (if any) 
Y = 0.5 * (1) +0.5(2) 
Using the above logic, a person of any age (above30) can find his loss of years life. 


    The above equations are arrived at using massive patient's data and curve fitting techniques. 
    Let us add years to our life using math.

    Nice way to quantify years of living based on belly size.

Your heart -you do not know

  Size and Location: The human heart is roughly the size of a clenched fist and is located slightly to the left of the center of the chest. Despite its relatively small size, the heart plays a crucial role in pumping blood throughout the entire body. Heartbeat Variability: The heart does not beat at a constant rate. The interval between heartbeats can vary, and this variability is considered a sign of a healthy heart. Factors such as breathing, emotions, and physical activity influence the heartbeat. Electrical Conduction: The heart's contractions are controlled by electrical impulses. The sinoatrial (SA) node, often called the "natural pacemaker," generates electrical signals that regulate the heartbeat and coordinate the pumping of blood. Blood Pumping Capacity: On average, the human heart pumps about 2,000 gallons (or 7,570 liters) of blood each day. Over a lifetime, this amounts to pumping enough blood to fill several Olympic-sized swimming pools. Heart Chambers and V...

THE WORK HORSE "="

    One cannot think of  a mathematical step without 'is equal to ' .  It balances right hand side and left hand side.  It aids simplification and manipulation of a mathematical expression. example: 2(A+B)  = C 2A+2B  = C         2A = C-2B           A = C-2B/ 2   In an electronic calculator,  the pressing of ' = " sign executes an asthmatic expression  or simply calculates.       In computer languages, it plays very important role.                                                                 A = B   When a computer looks at this expression, the value stored in the location named B is just transferred to the storage named A .  After execution both A and B will have the same value an...

How does your smart phone detect motion, steps, rotation, and location?

 How it works-1  An accelerometer in a smartphone is a microelectromechanical system (MEMS) device that measures acceleration and tilt. It works by detecting changes in motion by measuring the vibration or acceleration of the device. The accelerometer consists of a small mass suspended on a spring inside a sealed chamber. When the device is subjected to acceleration, the mass moves relative to the device, causing a change in capacitance that can be measured and processed by the smartphone's hardware. The accelerometer measures acceleration in three dimensions (x, y, and z) and provides data that the smartphone's software can use to determine the device's orientation, detect motion, and track changes in velocity and acceleration. The accelerometer is used for a variety of purposes in a smartphone, including screen rotation, motion tracking for games and fitness apps, and detecting the position of the device for navigation and location services. Additionally, it can be used t...
