¿Qué es envejecer? ¿Qué es más importante a la hora de envejecer, la herencia o el ambiente? ¿Podemos actuar sobre nuestro propio envejecimiento? ¿Qué tendríamos que hacer para envejecer bien?

Estas y otras muchas preguntas serán respondidas a los largo de este MOOC en el que se pretende transmitir conocimientos actualizados y científicos sobre cómo llegar a una longevidad positiva y saludable a la vez que se pretende motivar a los participantes en la puesta en práctica de una serie de comportamientos que conforman lo que llamamos estilos de vida activos y saludables. Así pues, esos conocimientos no serán suficientes para el cambio hacia un envejecimiento activo; ello dependerá de que cada uno de los participantes incorpore, como hábitos, esos comportamientos que sabemos influyen en un envejecimiento óptimo, lo cual requerirá de una actitud positiva y de la determinación, el querer realizar algunos cambios.

Partimos de la consideración de que el envejecimiento no tiene un claro inicio sino que “vivir es envejecer y envejecer es vivir” y consideramos que a todo lo largo de la vida hay crecimiento, estabilidad y declive. Desde luego, huimos de una visión simplista, exclusivamente positiva, del envejecimiento y dado que la edad está asociada a la enfermedad, la discapacidad y a otros problemas, tratamos de promover ciertas “soluciones” que llevan consigo lo siguiente: optimizar las capacidades físicas, mentales, afectivas y sociales; prevenir potenciales enfermedades y problemas y, en su caso, compensar o paliar existentes déficits.

Esas estrategias, soluciones comportamentales y estilos de vida protectores o combativos de factores de riesgo pertenecen a cuatro dominios esenciales: la mejora de la salud y la funcionalidad; promover el ejercicio físico y cognitivo regular; el mantenimiento y la optimización del afecto positivo y el control y, finalmente, la implicación familiar y social.

Este curso está dirigido a personas de cualquier edad que estén interesadas en envejecer bien. Va a requerir no solo el aprendizaje de conocimientos científicos sino una implicación personal de los participantes puesto que pretendemos, también, la introducción de cambios en la forma de percibir la vejez y en la incorporación de hábitos saludables que lleven consigo, a largo plazo, el desarrollo personal y la satisfacción con la vida.

Acerca de este curso

Si usted está interesado en aprender a hacer e interpretar pronósticos de ventas sin profundizar en las matemáticas, ¡este curso es para usted!

Podrá desarrollar la habilidad para entender en qué situaciones debe utilizar y aplicar los tipos de pronósticos basados en modelos existentes, vistos de una forma matemática muy práctica.

Comprenderá cuándo un pronóstico es bueno y cuándo no lo es.

Podrá presentar informes exitosos que le permitan tomar decisiones anticipadas y "acordes a la realidad de su negocio."

Think about the oldest and most familiar principles of American law, property and proportional liability, in a new and surprising way, and learn to apply economic reasoning to an especially important and interesting aspect of life.

This course examines the theories and policy debates over who can own real property, how to communicate and enforce property rights, and the range of liberties that they confer. It explores alternative economic, political, and sociological perspectives of property rights and their policy and planning implications.

This course provides an integrative forum for operations and manufacturing students and is the focus for projects in leadership, service, and improvement. It covers a set of integrative manufacturing topics or issues such as leadership and related topics, and includes presentations by guest speakers such as senior level managers of manufacturing companies. The subject is largely managed by students. Primarily for LFM Fellows and Masters students interested in focusing in operations and manufacturing.

This course is an intensive seminar on the foundations of analytic philosophy for first-year graduate students. A large selection of classic texts, such as Frege's Foundations of Arithmetic, Russell's Problems of Philosophy, and Wittgenstein's Philosophical Investigations, is covered in this course.
