For context: 4 out 301 spaceflights have resulted in fatalities, or 18 out of 546 people who have been to space.  13 people have died in training, but I have not been able to find the total number of people who have trained as astronauts or cosmonauts.  I suppose we would also have to account for health risks due to spaceflight: radiation exposure, accelerated aging, respiratory issues among Apollo astronauts due to lunar dust in their capsules, etc.  It&#x27;s certainly riskier than a desk job, but it still doesn&#x27;t seem <i>that</i> risky to me.<p>[1] fatalities in space: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_spaceflight-related_accidents_and_incidents" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_spaceflight-related_ac...</a><p>[2] number of spaceflights: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_human_spaceflights" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;List_of_human_spaceflights</a><p>[3] number of people who have been to space: <a href="http:&#x2F;&#x2F;www.worldspaceflight.com&#x2F;bios&#x2F;stats.php" rel="nofollow">http:&#x2F;&#x2F;www.worldspaceflight.com&#x2F;bios&#x2F;stats.php</a><p>[4] accelerated astronaut aging: <a href="http:&#x2F;&#x2F;lemire.me&#x2F;blog&#x2F;2015&#x2F;12&#x2F;01&#x2F;the-mysterious-aging-of-astronauts&#x2F;" rel="nofollow">http:&#x2F;&#x2F;lemire.me&#x2F;blog&#x2F;2015&#x2F;12&#x2F;01&#x2F;the-mysterious-aging-of-ast...</a><p>[5] Apollo respiratory issues: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Adverse_health_effects_from_lunar_dust_exposure" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Adverse_health_effects_from_lu...</a>
