Outline of life extension

Short description: Overview of and topical guide to life extension

The following outline is provided as an overview of and topical guide to life extension:

Life extension - study of slowing down or reversing the processes of aging to extend both the maximum and average lifespan. Also known as anti-aging medicine, experimental gerontology, and biomedical gerontology.

## Goals

* Biological immortality
* Indefinite lifespan
* Longevity
* Rejuvenation

## Longevity

* Centenarian
* Supercentenarian
* Longevity escape velocity

## Strategies

### Research and development

* Timeline of senescence research

### Available strategies

* Calorie restriction or protein restriction or intermittent fasting
* Exercise
* Geroprotector
* Senolytics

### Potential future strategies

* Cryonics
* Genetic therapies
* Cloning and body part replacement
* Cell replacement therapies (CRT)
* Strategies for engineered negligible senescence (SENS)
* Digital immortality through mind uploading
* Suspended animation
* Immunisation

## Aging

* Evolution of ageing
* Gerontology
* Pro-aging trance

### Hallmarks of aging

* Altered intercellular communication
* Cellular senescence
* Deregulated nutrient sensing
* Epigenetic alterations
* Genomic instability
* Loss of proteostasis
* Mitochondrial dysfunction
* Stem cell exhaustion
* Telomere attrition

### Causes of aging

* Cross-links
* Crosslinking of DNA
* Free radicals - atom, molecule, or ion that has unpaired valence electrons. With some exceptions, these unpaired electrons make free radicals highly chemically reactive towards other substances, or even towards themselves: their molecules will often spontaneously dimerize or polymerize if they come in contact with each other. They are countered to some extent by antioxidants.
* Glycation
* Advanced glycation end-product
* Lipofuscin
* Viral infections (acute or chronic)
