Time does not matter in Work. Force and Distance do.
F = 50 N
s = 0 The only work you have done is move the ball above your head. Thereafter you just held it.
t = 15 but no work is done. Tell your tired muscles that as they try and deal with holding a 5 kg mass above you head.
W = 0

Again from the last question you should be able to tell that time does not matter. The force is the same for both of you (that's why he's your identical twin).
So the work is the same. You both weigh the same. You both went the same distance.
