Taste

Taste, gustatory perception, or gustation is the sensory impression of food or other substances on the tongue and is one of the five traditional senses.

Taste is the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds. Taste, along with smell (olfaction) and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food or other substances. Humans have taste receptors on taste buds (gustatory calyculi) and other areas including the upper surface of the tongue and the epiglottis.

The tongue is covered with thousands of small bumps called papillae, which are visible to the naked eye. Within each papilla are hundreds of taste buds. The exception to this is the filiform papillae that do not contain taste buds. There are between 2000 and 5000 taste buds that are located on the back and front of the tongue. Others are located on the roof, sides and back of the mouth, and in the throat. Each taste bud contains 50 to 100 taste receptor cells.

Life Starts Now

Life Starts Now is the third studio album by Canadian rock band Three Days Grace. The album was released on September 22, 2009. The album was produced by Howard Benson. This is the second time in a row the band has worked with him, after the commercially successful One-X. Life Starts Now expresses a lighter lyrical mood compared to the band's previous album. It became the last ever Three Days Grace album under Jive Records until Sony Music Entertainment disbanded the label in 2011, and the first under Sony Music Entertainment.

Background and production

After being on the road for five years with Three Days Grace, bassist Brad Walst stated, "We all came home and got a hard dose of life," which the band then used to create a more "musically in-depth and personal album". He describes Life Starts Now as a record about "confronting life and how fragile it can be".

Pre-production for Life Starts Now began in January 2009 while the band began recording the music in Vancouver in March. The album was completed in August of the same year. After finalizing all aspects of the album, they officially announced that the album would be released on September 22, 2009.
