Theory of Life Span

Everyone wonder how we live in this world for some years. This kindles a tricky question how the life span differs for different people including other living things. Some may have shorter life in terms of days while for others it extend like centuries, starting from simple house flies to long living Tortoise and Turtles. How could this happen.. Why such variability among all..
This question and confusion arises because of our wrong notion and methodology which we adapted for calculating life span.
For your information all living beings have equal life span (VEDA). Wondering how.. Its simple to explain. Normally how we calculate a life span. By Time, isn't it? i.e. in terms of days, weeks, years to fall on. But this is wrong formula for life span estimation. Then how our VEDA clearly states that all have equal life span. And here is the answer for that,,..
Think in another dimension and perspective. It says life time is being calculated by our breath count. Yes our normal breathing time (Caution: Not based on Heart Beat Rate) decides how long we might live in this world. Let me explain with an example. We, the humans normally take breath 12-16 times per minute. Our life span app. goes upto 70-80 years. But considering Tortoise it usually breathe for 3-5 times/min. Nearly one third of ours. Hence its lifespan extends thrice than ours. This is how we should calculate our span. Through meditation we can bring down this breath count by 4-5/min. Thats how our saints and yogi's lived a long life in the past.
Please dont do research on this to contradict. This is a simple hidden and undeniable fact of life.
