The trouble with any definition of life that includes reproduction is that excludes the many examples of things we'd call alive but don't reproduce: the sterile, the elderly and the unlucky. So you end up having to be rub in a side order of "potential to reproduce" or "from a class that reproduces" which again muddy the issue and, even then, reproduction is, itself, not exactly a trivial concept to clearly define.
When it comes to multicellular organisms the definition says it can be broadly applied to include growth/development (ie cells dying and new cells being generated). The elderly are still hotbeds of reproducing cells, even if they lack any viable germ line cells.
What definition is that? Including growth and simple cell replication in reproduction is a very non-standard notion of reproduction, indeed.
