The human aging process can be characterized by progressive cellular degeneration, mitochondria malfunctioning, inflammatory responses, epigenetics modifications, and loss of tissue regenerative ability. The recent progress made in the field of longevity has revealed several promising treatment opportunities for prolonging a healthy lifespan in humans through epigenetics regulation, senolytics application, NAD+ precursors' intake, telomerase activation, and regenerative treatments. This review considers evidence from human studies about the impact of DNA methylation, cell senescence elimination, mitochondria recovery, enhanced immunity, tissue renewal, and cognitive reserve increase in human aging biology. According to findings based on human research, interventions involving senolytic compounds, Nicotinamide Riboside (NR), Nicotinamide Mononucleotide (NMN), and telomerase-linked regenerative treatment have the ability to contribute to improved metabolism, vascular functions, immunological resilience, and cognitive efficiency while reducing inflammatory processes and decreasing the number of senescent cells in a human body. In addition, comprehensive longevity approaches consisting of the mentioned interventions seem to possess combined benefits in terms of human longevity improvement. However, there are certain drawbacks that must be addressed when applying these interventions into clinical practice; namely, small sample sizes used in studies, lack of long-term safety testing, ethical issues, and inadequate biomarkers. Future directions in the research are discussed.

Eyelid twitching and involuntary facial muscle spasms have become common neuromuscular disorders due to stress, anxiety, sleeplessness, prolonged computer usage, exhaustion, and other external factors. The purpose of this review is to discuss various neurophysiological, psychosomatic, environmental, and medical aspects of eye twitching disorders such as eyelid myokymia, hemifacial spasm, and blepharospasm in highly stressed people. Human research demonstrates that chronic stress along with dysfunction in the autonomic nervous system plays an important role in neuromuscular hyperactivity and ocular muscle spasms. Magnesium is discussed in this review as an important nutrient for nerve signaling, muscle relaxation, and neurotransmitter function. Therefore, magnesium intake in combination with stress management methods like meditation, yoga, and sleep may help alleviate the symptoms of eyelid twitches. Neurological complications like hemifacial spasm and blepharospasm generally require the intervention of drugs, neurological procedures like botulinum toxin injection therapy, anticonvulsants, and microvascular decompression surgery. The review also touches upon the effects of prolonged muscular spasm within the eye muscles on emotions, occupation, and quality of life from a psychosocial perspective. While previous human-based studies have shed light on various clinical aspects of the subject, there remain certain issues like small sample size, variation in therapeutic protocols, and absence of longitudinal studies that underscore the need for further clinical research.
