Human Longevity: Where We Stand Now

 Human Longevity: Where We Stand Now

Humans are living longer than ever. A century ago, global life expectancy was about 35–40 years. Today, it’s over 70—and in some countries, it’s pushing past 85. This shift isn’t magic; it’s the result of cleaner water, better nutrition, vaccines, antibiotics, and advances in public health.

But adding years isn’t the same as adding healthy years. Many people spend their final decades battling chronic conditions like heart disease, diabetes, or dementia. That’s why the focus is shifting from lifespan (how long we live) to healthspan (how long we live well).

Science is exploring bold ideas: gene editing to repair DNA damage, drugs that slow cellular aging, regenerative therapies to replace worn-out tissues, and lifestyle programs tuned to individual biology. While no silver bullet exists, decades of research point to a few consistent factors—exercise, balanced diet, stress control, strong social ties—that not only extend life but keep it worth living.

The goal of modern longevity research isn’t immortality. It’s giving people more years of mobility, independence, and clarity—and making sure those extra years are ones you actually want to live.

سلمان عطا پاکستان میں کھجور کی کاشت تعارف کھجور کا شمار ان چند درختوں میں ہوتا ہے جو قدیم انسان نے اپنی خوراک کیلئے کاشت کرنا شروع کئے۔ موہنجو داڈو میں ملنے والے پانچ ہزار سال پرانی گٹھلیاں اس بات کی طرف اشارہ کرتی ہیں کہ برِصغیر میں یہ درخت ہزاروں سالوں سے موجود ہے۔ یہ درخت نہ ہوتا تو شائد عرب کے صحراؤں میں زندگی کا پنپنا ممکن نہ ہوتا۔ اس کا شمار فی ایکڑ سب سے زیادہ خوراک پیدا کرنیوالے پودوں میں ہوتا ہے . کجھور میں نر اور مادہ درخت علیحدہ علیحدہ ہوتے ہیں۔ ایک درخت تقریبا" سو سال تک ہر سال 70 سے 150 کلو تک کھجور پیدا کر سکتا ہے اور فی ایکڑ 150-120 پودے لگائے جا سکتے ہیں۔ پانی کی قلت اور نمکیات کی زیادتی کو بہت حد تک برداشت کرنے کی صلاحیت رکھتا ہے البتہ پانی جتنا زیادہ ہو گا اتنا بہتر پھل دے گا۔ غذائی اعتبار سے دیکھا جائے تو کھجور فائبر، وٹامنز (خصوصا" بی کیمپلیکس)، اور منرلز (کیلشیم، آئرن، پوٹاشیم زنک وغیرہ) کا بہت اچھا ذریعہ ہے۔ کھجور کی پیداوار کے اعتبار سے مصر، ایران، سعودی عرب، متحدہ عرب امارات اور پاکستان دنیا کے پانچ بڑے ممالک ہیں۔ پاکستان میں مکران (خاص اقسا...

Research Process in Social Sciences

Short introduction to Research Process in Social Sciences  Part 1 Salman Ata The   research process   is an organized, systematic way to state and answer questions and to solve problems. It involves different steps in a cyclic form which implies that it is a continuous process. There is no single “official” way to determine the steps in the research process and it is also difficult to assess where the actual research process begins. However before data collection a research problem, and indeed a research question should be defined without which data collected will likely be imperfect or useless. Moreover, decisions about the social setting intended for observation, sampling procedures and techniques should be made. The research process also differs somewhat from one discipline to another. There is no single “official” way to determine the steps in research process; however, outlines below do help to describe how research is done A) ...

PARADIGMS OF SOCIAL RESEARCH

PARADIGMS OF SOCIAL RESEARCH (Draft only) Mental model or frames of reference (belief system) (to organize observation and reasoning) shape our research designs. These frames or mental models are known as paradigms ( Bhattacherjee, 2012 ). It is a way to describe a worldview, informed by some philosophical assumptions about the nature of (social) reality ( Chilisa and Kawulich , 2012) . They are like colored glasses that control what we see and how we organize our thoughts about the observed world. According to Schwandt (2001), “ a paradigm is a shared worldview that represents the beliefs and values in a discipline and that guides how problems are solved ”. Different people have a different views of the observed phenomenon because they see social reality in different ways. For example, liberals and conservatives proposed different poverty reduction strategies as they see governments’ roles differently. To create a better economy, conservative may propose lowering taxes while...
