It was easier and fun to exercise when was a teenager and so on. Become lot less when gained almost 40 pounds in a month due to medication. Become even less interesting when would get hurt for exercising while overweight. Become a no-go when got a muscle strain for simply going downstairs because a physiotherapist pushed a bit too much and was under muscular fatigue.&lt;p&gt;I&amp;#x27;d prefer to take a bath and have some benefits that fell all that pain again and immobilize my leg and loose what I&amp;#x27;ve earned in the past 4 months.&lt;p&gt;For those who already like to exercise (or are willing to despite saying &amp;quot;I don&amp;#x27;t like, just like the benefits&amp;quot;, or any kind of wording of this idea), well, this study won&amp;#x27;t make a difference.&lt;p&gt;For me, yes, it makes.</text><parent_chain><item><author>zeteo</author><text>&amp;gt; Exercising (moderate physical activity) for 2-2.5 hours per week leads to a 20% reduction in all-cause mortality (not to mention its many other benefits).

<instructions>Your goal is to analyze the following comment and estimate how highly it will be upvoted by the Hacker News community.</instructions><comment><author>joshgel</author><text>I agree with your comments entirely. I&amp;#x27;ll also add, however, that even though this is cohort data 1) there is A LOT of data, almost all of it in agreement for hundreds and hundreds of studies, over millions of person years and 2) there is pretty strong evidence of a dose-response relationship. Both of those two points &lt;i&gt;help&lt;/i&gt; (though don&amp;#x27;t entirely eliminate) the weaknesses inherent in cohort data.</text><parent_chain><item><author>zeteo</author><text>&amp;gt; Exercising (moderate physical activity) for 2-2.5 hours per week leads to a 20% reduction in all-cause mortality (not to mention its many other benefits).
