How to Achieve Your Life Goals – A Roadmap to Purpose and Fulfillment Introduction Everyone has goals—some grand, some simple. But turning these dreams into reality requires more than just desire. It requires strategy, discipline, and a clear vision. According to a study by Dominican University of California, people who write down their goals are 42% more likely to achieve them . In this blog, we’ll explore a practical roadmap to help you set, pursue, and achieve your life goals with focus, resilience, and clarity. 1. Get Crystal Clear on What You Want The first step is defining your goals . Vague ambitions like “I want to be successful” are hard to act on. Instead, be specific: "I want to start my own online business by next year." "I want to write and publish a novel in 12 months." Clarity creates direction. Tip: Use the SMART framework: Specific Measurable Achievable Relevant Time-bound 2. Break Big Goals Into Small Steps Major goals can fe...
Why Further Increasing Human Life Expectancy Will Be Difficult
In the 20th century, human life expectancy saw remarkable growth, largely due to advancements in public health, medicine, and technology. Between 1920 and 2020, the average lifespan doubled. However, recent studies show that these increases are slowing down, and extending life expectancy significantly beyond current levels may be harder than we think.
A new analysis published in Nature Aging titled "The Implausibility of Radical Life Extension in the Twenty-First Century" examines these limits. The study suggests that even with modern medicine, our bodies might not be capable of significantly longer lifespans without breakthroughs that address the aging process itself.
Key Findings from the Study
S. Jay Olshansky, a professor at the University of Illinois Chicago and lead author of the study, shared insights on this issue. He argues that human life expectancy may have already reached a plateau. According to Olshansky, "As long as we live now is about as long as we're going to live," indicating that unless radical advancements are made, future life expectancy gains might be minimal.
The study analyzed life expectancy data from regions where people tend to live the longest, such as Australia, France, Italy, Hong Kong, Japan, South Korea, Spain, Sweden, and Switzerland, covering the period between 1990 and 2019. While life expectancy increased during this time, the rise was modest, only about 6.5 years over nearly three decades. In fact, the chances of people reaching 100 years of age remain quite low — 5.3% for women and only 1.8% for men, according to the study.
Why Life Expectancy Has Plateaued
In the 20th century, advancements in healthcare, such as vaccines, antibiotics, and better sanitation, drastically reduced deaths from infectious diseases and other health conditions. This led to a significant increase in the average lifespan. However, as we move further into the 21st century, the challenges to extending life expectancy are more complex.
The study found that while modern medicine helps people live well into their 70s, 80s, and even 90s, pushing life expectancy much beyond that is difficult. One major reason is that aging itself becomes the limiting factor. Even if we eliminate deaths from heart disease, cancer, or other illnesses, the body’s natural aging process will still cause organ systems to fail. According to Olshansky, "Declining functions of internal organs make it virtually impossible for bodies to live much longer than they do now."
The Role of Aging in Limiting Lifespan
The body's natural aging process involves the gradual breakdown of cells and tissues, making it harder for our organs to function optimally as we grow older. This slow deterioration is what ultimately limits human longevity. Without a way to slow down or reverse aging, life expectancy gains will remain limited.
While current medical advancements focus on treating diseases, these treatments may not extend life expectancy beyond the current limits. Diseases like cancer and heart disease can be managed, but they are not the primary obstacles to significantly longer lives. The real challenge is addressing the aging process itself.
Can Science Help Extend Lifespan Further?
The study suggests that to dramatically extend life expectancy, scientists would need to develop treatments that slow down or reverse aging. While several drugs are being tested on animals for their potential to increase lifespan, these breakthroughs are still in the early stages.
For instance, metformin, a commonly used diabetes drug, has shown some promise in slowing aging in animal studies. Researchers have tested it on monkeys and found that it can extend their lifespan. However, it remains unclear whether these results can be replicated in humans. Even if such drugs prove effective, it will likely take decades of research and testing before they are widely available for human use.
Why Reaching 100 Might Be Unlikely for Most
Some scientists in the past predicted that many people born after 2000 would live to be 100 years old. However, the new study suggests this is unlikely. According to their analysis, only a small percentage of people in the longest-living regions are expected to reach 100. For girls born recently in these areas, there is only a 5.3% chance of living to 100, while boys have an even lower chance at 1.8%.
This suggests that while modern medicine has allowed people to live longer, there are natural biological limits to how long the human body can last. Without radical advancements that address aging, it’s unlikely that we will see dramatic increases in life expectancy anytime soon.
What Does This Mean for the Future?
The findings from this study have important implications for how we think about aging and healthcare. While it’s important to continue improving treatments for diseases like cancer and heart disease, these advancements will not be enough to push life expectancy beyond current limits.
If scientists want to significantly extend human lifespan, they will need to focus on the aging process itself. This will likely require breakthroughs in fields like genetics, stem cell research, and regenerative medicine. Until then, the best we can do is improve the quality of life in our later years, rather than expecting a significant extension of life expectancy.
Conclusion
For much of the 20th century, the dramatic rise in life expectancy was driven by improvements in public health and medicine. However, as we move further into the 21st century, it’s becoming clear that increasing life expectancy will be much harder. While modern medicine has helped many live into their 80s and 90s, pushing the average life expectancy beyond that will require new breakthroughs in science, particularly in addressing the aging process.
Though there is some promise in current research on anti-aging drugs, it will likely be many years before we see any significant effects on human lifespan. In the meantime, the best approach is to focus on improving healthcare and quality of life for people as they age, rather than expecting radical life extensions in the near future.
