"Live a good life. If there are gods and they are just, they will not care how devout you have been, but will welcome you based on the values you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memory of your loved ones. I am not afraid."

comment Statistical method for characterizing the relationship between body mass and metabolic rate
This is more a statistics than biology question, but before choosing a statistical test it is essential to visually inspect your raw data. Is your data skewed at all? BMI in the normal population already has a Gaussian distribution, and I expect metabolic rate also would - so unless you have a reason to log-transform I would not do this. For me there is nothing wrong with performing a linear regression to test the linear association between these traits, and then also test for any non-linear effects (perhaps by including an interaction term between them).

comment Can brain cells move?
Great answer. Glial cells (resident, supporting cells) also include resident immune cells, such as microglia, which are related to the monocyte lineage

comment FoxO gene(s) and aging
One of the problems here would be that the mechanisms of the effect of FOXO on longevity are not fully understood, and likely differ between the species. In humans, for instance, the evidence is not very strong (ncbi.nlm.nih.gov/pubmed/25199915). Make your question specific and it will be far more answerable... in fact you could break this up into several questions "What role do FOXO genes have in stem cells", "What role do stem cells play in aging"... etc

comment Do larger multicellular organisms have an increased risk of mutation and thus cancer?
@Mew interesting question. Had a quick search and could not find a systematic study. The closest I could find is a report suggesting that BMI is positively associated with some adult cancers in humans (PMID: 18280327), however this could be confounded by a number of issues (>BMI could indicate unhealthy lifestyle? inactivity, smoking, drinking... only suggestions, but you can see what I mean). I can see that the logic of "large people have more cells" would imply higher cancer rates, but I don't see any evidence for this.
