We are in our mid 70's.  Came together fairly straight forward.  Carefully follow the directions.  The parts are labeled which helps in gathering the right parts for the particular step you are on and easing the construction.  Having a 6+ ft nephew helped greatly with the construction/installation of the roof section.  Oterwise a bit much for 5.5 ft seniors alone.  Immediately after construction/installation completed had significant thunderstorm with winds and rain.  Checked on shed the next morning and all was quite well with it, intact and dry inside even though it was not yet filled with our garden stuff.  So far, quite pleased.
