Sometimes, illnesses become a real mystery for doctors. Alecsa will meet an infectious disease specialist whose job is to diagnose and treat rare and complex conditions. We see their big brown trucks everywhere delivering packages to doorsteps. Alecsa learns what it takes to be a UPS driver and package handler. Trendy boutiques are popping up everywhere. Alecsa will visit one and learn how they serve their clientele in a more personal way than the big department stores and what it takes to own a fashion boutique.
