                        new AgeValidator(et_age),
                        new MobileValidator(et_mobile),

                .map(validator -> new ClientInfo()
                        .setName(validator.from(et_name))
                        .setAge(validator.from(et_name))
                        .setMobile(validator.from(et_name))
                        .setArea(validator.from(et_name)))

                .doOnNext(data -> toast("Saving Client info"))
//               .flatMap(data -> {}) --> save in database
//               .flatMap(data -> {}) --> send to server
