What have you touched today?
Can you remember everything you've touched today? Argentine-born designer, Paula Zuccotti, asked 62 people to make a note of all the objects they handled in a 24-hour period, then gather them together for a snapshot of their lives.
"Many of the things we know about past civilisations are from insights gathered through their objects," says Paula Zuccotti.
"Tools, utensils, clothes, manuscripts and art have taught us about the type of work they did, what they hunted, grew and ate, and how they expressed themselves."
So with that in mind, she decided to make a photographic "time capsule" of 2015 and build up portraits of people through their possessions.
"I was looking for lifestyles that intrigued me, some of which are disappearing. I went to Arizona looking for a cowboy and to Tokyo because I wanted to document the life of a geisha," says Zuccotti.
Twenty-three-year-old David, an American cowboy, and Eitaro, a 32-year-old Japanese man who learnt to perform the role of a geisha from his mother fitted the bill.
While she was working on the project, Everything We Touch, Zuccotti found that, on average, people handled 140 objects per day - excluding structural fittings such as taps, handles and light switches.
She laid out items chronologically for each photo, and in many cases the objects give away a significant amount of information about the person who touched them - these three pictures represent the lives of a cook, a baby and a butcher.
Some people weren't able to collect everything they touched though - Piedad is a cloistered nun in Madrid who only provided Zuccotti with her coif, black veil, holy habit, scapular, Bible and rosary.
The nun, originally from Ecuador, hasn't left the convent for more than 28 years.
"So I visited her," says Zuccotti. "As we conversed through bars, the bag of belongings Piedad wanted me to have appeared through a window. When I enquired where the other objects that she would have touched were, such as her toothbrush, mug and comb, she looked at me and said 'I can't.'"
"I think this project does not have an ending," says Zuccotti, who would now like to photograph "new places, new topics, specific people" including the worlds of the rich and famous and those who live in the public eye.
She can't help wondering, if she were to re-run the project in 10 years what new objects would appear and what would be extinct.
