Just pointing out , there was a typo . <| sep |> Does anyone else feel the FHR is a better RPR ? Seriously , the RPR drops to 7 shots so quickly . <| sep |> Sorry that was my fault , I got hit by the automod right after for not naming a location . <| sep |> No such thing as a sleep deficit , you cannot make up for lost sleep , 8 hours is 8 hours , no matter if you stayed up for 50 , 8 hours will do the same as if you were up for 16 <| sep |> Apologies for jumping the gun . <| sep |> They alloy gold with copper hence you may have 14 K gold , which is cheaper and more durable than the pure gold 24 K . There is also an alloy that is 3 Titanium to one part gold and it is extremely strong and biocompatible but also very expensive . They plate with gold so that mostly jewellery , looks like they ' re made of pure gold .
