Achoo blues

Twice, when donating blood platelets to the Red Cross, I've started sneezing uncontrollably. Assistants respond immediately by giving me Tums, a brand of antacid indigestion tablet. Their explanation is that Tums restores my calcium balance.I understand how my calcium could get out of whack when my blood is being removed, filtered and given back to me without platelets, but what does this have to do with sneezing?Heather Hallen, East Lansing, Michigan, US

What could cause this?Michelle, Johannesburg, South Africa(Image: enrika79, stock.xchng)

Ride the curves Why are velodromes shaped the way they are? What's the science involved?Specifically, why do they have such high curves, especially as hardly any cyclists seem to venture up there, and why do they have sloping straights?
