Question

Problem,2.1. Dsigning a daily routine for as ini ias biud to be around 110 years This Given: The longest life span of an average human has been found to be around 110 years. This is revealed to be strongly dependent on the amount of food intake along with the amount of exercise executed. Let Y be the life span in years, X,, the number of hours of exercise per week, and X,, the kilogram of food intake per week. Find: Y f(X, X) which gives a maximum Y of around 110 years, and that the corresponding values of X, and X, are somewhat realistic. Include nice plots showing the variation of Y with respect to X, and X. List two other key factors which probably should also be included.

Answer 1

if y= f(x1, x2) which is life span in years a function of kilogram of food intake per week and the number of hours of exercise per week then the corresponding values of x1 and x2 should be somewhere around 7 hours a week and 2 kilograms of food per week. the values have taken so because to stay healthy and feet a human should burn a required amount of calorie per day by either exercising or doing any other work which burns calories. and secondly the amount ones body requires to function is around 2200 calorie which we can convert to 2 kg per week.

now if the two varies say the x1 has declined to 4 or 5 hours a week and the x2 has increased to 3 kg per week then the person might suffer from obesity in future and the life expectancy will decline from 110.

two other key factors which should also be added here are mental stability or mental peace of a person which is a very important factor in determining the life span and also health status of the person which also plays a very important role in determining the life span.
