My brother passed away 2 weeks ago. Had lost a lot of weight. In the couple days up to his death had to help him up several times. Could barely help him up he was so heavy. Using all my strength and him helping too. Not buying this for a second. Also same when a sat with a frail tiny woman who probably weighed 90 lbs. could barely do it. Weight is weight. Regardless if it’s a person or inanimate object. No one can lift over 100 lbs that easy without effort.
