Emma: Guys, are you in Sucre now?
Kate: No, I'm still in Europe :P
Jose: Yes, why?
Emma: I thought about visiting
Marie: nice, come here
Jose: anything happened?
Emma: i think I'm experiencing some little troubles because of the altitude here
Jose: nausea? Headaches?
Emma: yes
Jose: it may be altitude sickness, Sucre is much lower but still quite high above see level
Jose: around 2800m and altitude sickness starts at 2500
Emma: yes, but La Paz is 3600m, I think it'll make a difference
Jose: sure! So come here as soon as possible :)
Emma: I'll check the connections and let you know, thanks!
Emma wants to visit Jose and Marie who are in Sucre because she thinks she's got altitude sickness in La Paz. Kate is still in Europe.
