Is this true lol, im not sure?

Well, to begin with I have had lots of people tell me that as you age you may get fatter, but who knows, well im not skinny im far from it, I have a pretty big gut, I was woundering this, Ok my dad was never really fat but when he got older he did, he almost went 300 pounds and hes almost 7 foot, my mom is short and everybody says she has a gettoh booty lmao, but anyways, is it possible that i will get fatter to since my dad did, all 3 of my aunts are fat, and they never were when they were younger so may this happen to me, thanks to all who answers lol
