Summery: Human existence and their health rely on their intellectual interactions with ecosystem which eventually accompanies brilliant technological innovations. At par with the technological progress, humans also have been facing several intimidating communicable and non-communicable diseases. Amidst such disease threats, humans have discovered multiple ways to uplift the average life span all over the globe but still not up to the fitness benchmarks of healthy ageing trajectory. COVID-19 has specifically revealed the fragility of humans as they continue succumbing exponentially to the interactions of this communicable disease with their existing noncommunicable diseases like hypertension, cardiac pathology and diabetes. In human evolution, the COVID-19 pandemic could be the most perfect synapse or intersection of non-communicable diseases with this transmissible disease leading to a situation that can be even named as "Global Medical Stampede" characterized by sudden increase in the number of patients requiring life-saving procedures for which there is lack of adequate manpower and technological support in health care system. This whole chaotic scenario could easily trigger acute psychological and physiological stress primarily caused by fear among the public favoring the frightening consequences of the pandemic. This article aims to suggest refinement in public health paradigms to enable preparations to face such disease threats from the immediate future without further procrastination.

The entireness of life is to gain energy to (i) support growth and maturation of the body (ii) defend and control diseases (iii) build survival skills and competence and (iv) lengthen the lifespan. Quite obviously, such magnificent energy is derived by consuming food in diverse mixtures and patterns. Are we curious and equipped enough to learn the efficacy of dietary practices at individual and community level? The well-known recommendation of Sir. Hippocrates has been "If we could give every individual the right amount of nourishment and exercise, not too little and not too much, we would have found the safest way to health". But in general, the health care system has been rarely giving importance to exercise and nutrition as the principal determinants to facilitate enhancement, restoration and maintenance of health and fitness of the individuals. On the other hand, the researches and advancements in the domains of Exercise and Nutrition have been establishing the realities of their tremendous health and therapeutic benefits. It is also clearly evident, neither the general public nor the patients are completely benefited by the modernized practices in the field of Exercise and Nutrition. The best example is patients who underwent Anterior Cruciate Ligament (ACL) surgical repair inevitably presenting thigh muscle atrophy that appears as a major setback for rehabilitation, though this surgical complication could have been prevented by adapting right amount of scientific nourishment and exercise. Is it not important for Physiotherapists to be critical about such adverse outcomes of the medical procedures? Therefore, Physiotherapists must expedite acquiring skills and experience to strongly participate in public health predominantly relying on Exercise prescriptions. In order to ensure the effectiveness, it also becomes indispensable for Physiotherapists to collaborate with the Dietitians, so that suitable hydration, calories and nutrients (macro and micro) are supplied to blend its therapeutic benefits with that of the exercises for general public health and specific rehabilitation regimens of communicable and non-communicable diseases. It is also need of the hour to augment interdisciplinary and transdisciplinary approaches in the medical field apt for the stressors of the contemporary world and the evolutionary stage of humans to not only ensure the healthy human life span but also the sustainability of human life on the Earth.

Every citizen deserves a lengthy, healthy and successful life. Survival competence and successful ageing basically require (i) ability to counteract gravitational force through adequate muscle strength, flexibility and postural control (ii) healthy nutrition (iii) optimal respiratory efficiency at rest and during physical activity (iv) mental health and (v) supportive family. Lifespan of people is basically under the control of both individual and community participation. The burden for the individual after acquiring either communicable or non-communicable diseases is always unique, based on numerous variables like age, gender, socioeconomic status, occupation, lifestyle, severity of the disease, co-morbidities and access to legitimate health services. If the burden of the morbidity is not alleviated effectively, various crippling effects interweave and lead to irreversible loss of structures and functions, eventually deteriorating or destroying the competence to sustain an occupation or the level of independence. Mishaps, calamities and wars are also capable of exerting immediate effect to cause irreparable damages in the body (burns, spinal cord injuries, head injuries, fractures) forcing the sufferer to endure a troublesome life. Though harms to the body are unpredictable events, the extent at which every individual and the community as a whole are prepared with skills and technology to encounter them, controls the outcomes. Some disease states demand prolonged or lifelong health care that relies on affordability and family structure. On the other hand, completely costless health services are unrealistic and unsustainable to private sectors or private practitioners in the medical field, excluding sporadic exceptions where the health care is rendered on humanitarian basis. To certain extent, volunteers could provide different types of support using limited resources (few examples are walking aids, medicine supply, water supply, food supply, housing, blood donations, medical camps) to save or sustain life. But very often, many diseases require extensive interdisciplinary approach where multiple specialties are involved, so the total cost of the medical procedures (diagnosis and treatment) get elevated, due to which the deprived will be forced to limit or avoid or procrastinate treatments facilitating chances for the disease to mature incurably. The rehabilitation of patients is explicitly complicated but prevention of diseases looks less complicated if the public health model accentuates its focus on exercise, nutrition and health education to powerfully resist morbidities and premature mortalities through integrated efforts of health care professionals and all other overlapping domains. Based on substantial literature support, this article proposes a framework ‘SHARE’ to encourage necessary refinements to flourish the civilization as scrupulous as possible. It is also need of the hour for professionals of various disciplines to examine how their expertise could support this framework. KEY WORDS: Public Health, Life Expectancy, Salutogenesis, Mortality, Morbidity, Exercise, Nutrition, Epidemiology, Spiritual Intelligence, Population ageing.
