I wear an HR monitor and try to keep my heart rate 80 % of my max . Figuring out my max HR is a fairly torturous experience though . I can usually only hit it in the final kick of a 5 K race when my body is screaming at me to stop . e oh fuk didn ' t read your last sentence ha . so , uhh , buy a monitor . <| sep |> heres the link en <| sep |> It ' s like an echo chamber in here . <| sep |> It was probably unfair of me to say almost any , but yes . They ' ll often have a cheaper board inside , several cut corners and missing several input outputs etc . <| sep |> I think it could make some sense . This US is apparently unconcerned with repeated occasions of UFOs and extensive destruction by unknown people in a town in Delmarva , which isn ' t exactly that far away from D . C . What if they were Martians , or worse , communists ? A world where the US never stepped up to repair a broken world , and slipped into the paranoias and brinkmanship of the Cold War , would probably be this lazziefaire with national security . Though I am a big fan of alternate history , so I ' m probably prone to over thinking this stuff .
