INVESTING QUESTION

Hey guys,

So I just turned 30(M) I have about 45000K sitting in cash in my TFSA I'm looking for some feedback on the best splits for ETF investments. I know a bit but some of you guys are experts. So I'm looking for basically somewhat high risk options. I want to have aggressive growth and some with reinvesting divendends. Any opinions on these topics would be awesome. Also it doesn't have to be just healthcare and biotech but I've noted a shift in the market towards them.
