Diabetes affects our blood vessels and nerves and therefore can affect any part of the body. However, certain parts of our body are affected more than other parts.
I don't think dogwoods have (much?) scent, maybe just lightly floral. The white petally looking things are not actually petals they are bracts, like a poinsettia has. There's something called an English dogwood that is very fragrant, but it isn't a true dogwood and is also known as mock orange. Bradford pears have a smell that this author described as sweaty socks, so if your tree doesn't smell very good that's probably it: http://www.gardenguides.com/106133-dogw ...
What do you smell like? I mean, really smell like? And WHY do you smell like you smell like? The natural odors of most animals, besides those like skunk musk, are actually a result of bacteria digesting certain secretions and releasing tell-tale scent compounds. When dogs smell each othersâ rear ends, they arenât really smelling each other (so to speak), they are smelling the characteristic odor products.
