For example, a lot of older guests will not stay for the entire reception, so if you plan to cut your cake and do the bouquet toss near the end, they will either leave early and miss it or will have to stay a lot longer than they are comfortable.

Consider cutting your cake right after you are announced in and dance your first dance - all eyes are already on you, your caterer can cut the cake for serving after dinner, and older guests will be around to enjoy that special moment.

And you will still look fresh!
