To date, four types of HTLVs (human T-lymphotropic virus 1 [HTLV-I], human T-lymphotropic virus 2 [HTLV-II], HTLV-III, and HTLV-IV) and four types of STLVs (STLV-I, STLV-II, STLV-III, and STLV-V) have been identified. HTLV types HTLV-1 and HTLV-2 viruses are the first retroviruses which were discovered.

The position of goalie in lacrosse is probably one of the most intense positions of all sports. Essentially, you must play catch with people at a very high speed. Unfortunately for the goalie, most people don't throw at his stick. The goalie wears additional protective equipment: throat guard and chest protector. A goalie stick is typically of normal length, 40-50 inches, with an extra wide head. Unlike goalies in hockey, lacrosse goalies must be very mobile.
