today was difficult. tried to work on my truck. seems to be one of my most difficult tasks. the positions and such tire me. truly sux because i do lots of mechanical work. did it professionally for 14 years. the really odd thing is that my regular work as a contractor seems much more physically demanding yet tires me much less. i have difficulty lifting over my head but am able to climb ladders and handle heavy tools with little difficulty. when i spend 15-20 min. leaning over a motor i feel like i need to lay down. my neck gets especially sore looking down. like my head weighs a ton. wierd???
