The body adds weight, loses it, retains water, areas of the body expands etc, generally/simply the body ages as well. (It's the reason it should be well taken care of through the food you eat, exercises and generally keeping it in top shape so the process doesn't come as a shock or badly).
The body changes over the years, right from puberty with hormones raging and then finally 'relaxing' at a point. Some changes don't come as a total surprise while some do, some are not in the least bad (hello matured body!) while some are totally normal as they come with age!
