Caution: Do not attempt to perform forward bends without proper training and equipment. Seriously, don't try it at home.
In fact, just don't try it anywhere. We don't want to have to send a team of highly trained professionals to extract you from the ceiling fan or whatever.
Also, be aware of your surroundings. Forward bends are not recommended in crowded areas, such as shopping malls or IKEA.
And don't even get us started on forward bends during rush hour. Just no.
